We have that the following two points lie on the line:
• (-2, 0) and (4, 6)
And we need to find the equation of the line that passes through both points.
To find the equation of the line, we can proceed as follows:
1. Apply the two-point equation of the line, which is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]2. We have to label both points as follows:
• (-2, 0) ---> x1 = -2, y1 = 0
• (4, 6) ---> x2 = 4, y2 = 6
3. Now, we can substitute the corresponding points into the two-point equation of the line:
[tex]\begin{gathered} y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1}) \\ \\ y-0=\frac{6-0}{4-(-2)}(x-(-2)) \\ \\ y=\frac{6}{4+2}(x+2) \\ \\ y=\frac{6}{6}(x+2) \\ \\ y=x+2 \end{gathered}[/tex]Therefore, we have that the slope of the line is m = 1, and the equation of the line is y = x + 2.
Therefore, in summary, the equation of the line is y = x + 2 (Option D).

Write the equation that is parallel to 2x+y =4 going through the point (-1,3)
Answer:
2x +y = 1
Step-by-step explanation:
You want the equation of a line parallel to 2x+y=4 through point (-1, 3).
Parallel lineA parallel line will have the same slope, which is a function of the ratio of the x- and y-coefficients. Hence, the equation of the parallel line can use the same coefficients. It will have a constant suitable for the given point.
given: 2x +y = 4
parallel: 2x +y = c
through point (-1, 3): 2x +y = 2(-1) +(3) = 1
The equation of the parallel line is 2x+y = 1.

The quadratic equation is of the form y = ax² + bx + c
In algebra, a polynomial function with one or more variables in which the highest-degree term is of the second degree is known as a quadratic function, a quadratic polynomial, a polynomial of degree just 2, or simply known as a quadratic.
x is the only variable. A parabola with its axis of symmetry parallel to the y-axis represents the graph of a univariate quadratic function, as seen to the right.A quadratic equation is produced if the quadratic function is set to zero. The roots of an univariate function are the solutions to the univariate equation.When authors speak to a quadratic polynomial, they may mean "having degree exactly 2" or "having degree at most 2". If the degree is less than 2, this scenario may be referred to as a "degenerate case." Which of the two is intended will typically depend on the context.In some circumstances, like in the instance of a second-order polynomial, the word "order" is used to denote "degree." The word "degree of a polynomial" refers to the highest degree of a non-zero term in a polynomial, whereas the term "order" typically refers to the lowest degree of a non-zero term in a power series.Complete question: The table represents a quadratic function.

Sheila's mapping diagram doesn't represent a function because it includes the points (3, 6) and (3, 6) and fails the vertical line test.
What is a mapping diagram?An illustration of two circles that depicts the relationship between input and output values is known as a mapping diagram. By drawing an arrow from one x-value to its corresponding y-value, the x-values (inputs) in the image are transferred to the y-values (outputs).
It does not represent a function because the same input value, 3, is mapped to more than one output value, 3 and 6. Her relation has the following ordered pairs: (1, 1), (2, 2), (3, 3), (3, 6), (4, 4), 5, 5), and (6, 6). Since both (3, 3) and (3, 6) have the same x-coordinate, the relation fails the vertical line test and is not a function.

It should be noted that when multiplying powers you add rather than multiply the exponents in order to give an accurate value as multiplication do powers means the addition of the powers.
How to illustrate the information?Exponentiation is a mathematical process that involves the base b and the exponent or power n. It is represented as bⁿ and is pronounced as "b to the n."

Step-by-step explanation:
the fraction for 0.23 repeating is 23/99
you add 8 in front of it
8 23/99 is the mixed number version
for the fraction version you must multiply 99 to 8 and then add it to 23

Diego drew a scale drawing of the elementary school. The scale he used was 9 millimeters : 4 meters. In the drawing, the schoolyard is 324 millimeters long. What is the length of the actual schoolyard?
The length of the actual schoolyard given the scale is 144 meters
What is the length of the actual schoolyard?A scale drawing is either an enlarged or reduced image of another image or object. A scale drawing is enlarged or reduced using a scale. The scale drawing is usually reduced at a constant dimension using a scale. A scale is the ratio of the dimensions of the scale drawing and the dimensions of the original image.
Length of the actual schoolyard = (length of the school yard x scale of the schoolyard) / scale of the drawing

The new bookkeeper at Karlin Construction Company was asked to write off two accounts totaling $1,610 that had been determined to be uncollectible. Accordingly, he debited Accounts Receivable for $1,6
10 and credited Bad Debt Expense for the same amount.
The thing that is wrong with the bookkeeper’s entry assuming Karlin uses the allowance method is that the company uses allowance method and thus the write-off entry would not be to bad debt account.
How yo illustrate the information?
It should be noted that because the business is using the allowance approach in this instance, the write-off entry would not be to the account for bad debts. To write off an account, a debit must be made to a separate account that is kept as an allowance for dubious accounts.
Since the receivables would not be collected, the accounts receivable account would be credited. In this case,the write off isn't appropriately illustrated in the account.

Given that,
In the picture, There is graph with a triangle.
The triangle is SNZ.
We have to find the reflection across y=3.
We have to draw a line on y=3.
On the line y=3,
Z point is there so it will be same that is (5,3).
Now, the point S is on (5,1)
Here, y is 1 that is 3+2=5
So, we take the reflected S point as (5,5)
Now, the point N is on (1,4)
Here, y is 4 that is 3-1=2
So, we take the reflected N point as (1,2).
Therefore, we get the reflected triangle of y=3 as (1,2),(5,3) and (5,5).
