Graph the line with slope 8 and y-intercept −8.
To create the slope 8, you would have to do the rise over run:8/1. which means u go up 8 units and to the side one unit and you keep doing that. And since the y-intercept is -8, then you start your first point at -8 and continue to go up.
The graph is attached below:
What is graph?Graphing basic functions like linear functions and quadratic functions is easy. The basic idea of graphing functions is
Identifying the shape if possible. For example, if it is a linear function of the form f(x) = ax + b, then its graph would be a line; if it is a quadratic function of the form f(x) = ax2 + bx + c, then its a parabola.
finding some points on it, by substituting some random values of x and finding the corresponding values of y by substituting each value into the function.
For graphing quadratic function also, we can find some random points on it. But this may not give a perfect U-shaped curve. This is because, to get a perfect U-shaped curve, we need where the curve is turning. i.e., we have to find its vertex. After finding the vertex, we can find two or three random points on each side of the vertex and they would help in graphing the function.
Given:
slope= 8
y- intercept = -8
So, the equation can be
y= mx+ c
y= 8x - 8

A square window has an area of 1,232 in2. (a) What is the length of 1 side of the window? Round your answer to the nearest tenth. Show all of your work. (1 point for the correct answer and 1 point for showing how you got your answer)
x = length of one side.
1,232in^2 = x^2
Take the sqrt of both sides.
35.1 in = x
The length of one side = 35.1 in
Step-by-step explanation:
We know that,
area of square = a²
→ 1,232 = a²
→ a = √1232
→ a = 35.0 in
Nearest 10th = 35.1 in

7. The steps below show Cam's work in solving an equation. Circle the line where he makes a mistake. Then, find the correct solution to the equation.
Answer:
Error was at the fourth line: 12 = 16x
Correct solution: x = ½
Step-by-step explanation:
Let's solve the equation step by step to find the correct solution, and also, to find out at which line Cam made a mistake.
10 - 2x = 19x + 2 - 5x (given)
10 - 2x = 19x - 5x + 2
10 - 2x = 14x + 2
Add 2x to both sides
10 - 2x + 2x = 14x + 2 + 2x
10 = 14x + 2x + 2
10 = 16x + 2
Subtract 2 from both sides
10 - 2 = 16x + 2 - 2
8 = 16x (this is where Cam made an error, at the fourth line. He wrote: 12 = 16x. It seems Can only subtracted 2 from the right, then added 2 to the left. Subtraction property of equality was not properly done.)
Proceeding further with our calculation, we would divide both sides by 16
8/16 = 16x/16
½ = x

1) Given the following problem: I am thinking of a number. If you double the number and add 10, the result is 22.
What is the number?
a) Write a detailed explanation of the solution of the problem using the problem solving strategy: Work Backwards
Answer:
the number is (((6))))
Answer:
The answer is 6
Step-by-step explanation:
What wanna start out with finding the difference by subtracting 10 from 22. This would give you the difference of 12. Since its 'double the number', we are going to find the quotient of 12 / 2 = 6. You will then end up with the answer 6.
Solve the following system of equations. {y=−2x−92x+3y=−3 Write your answer as an ordered pair in the form (x,y).
Answer:
(x, y) = (-6, 3)
Step-by-step explanation:
Maybe you want to solve ...
y = -2x -92x +3y = -3Use the first equation to substitute for y in the second:
2x +3(-2x -9) = -3
2x -6x -27 = -3

Dale made a model of a lighthouse using a 4 inches=50 feet if the lighthouse is 120 feet tall, how tall is his model
Answer:
8 2/5 inches!
Step-by-step explanation:
The lighthouse is 120 feet, and 4 inches of height on the model equals 50 feet of height on the lighthouse. 100 divided by 50 = 2, and 4 multiplied by 2 is 8. 20 divided by 50 = 2/5, so the answer is 8 2/5 inches. :)

What is the equation of the line that has a slope of -2 and passes through the point (-1, 2)?
y = -2x − 4
y = -2x
y = -2x + 4
None of these choices are correct.
Answer:
The answer is
[tex]y = 2x[/tex]Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (-1 , 2) and the slope is - 2
The equation of the line is
[tex]y - 2 = - 2(x + 1) \\ y - 2 = - 2x - 2 \\ y = - 2x - 2 + 2[/tex]We have the final answer as
[tex]y = 2x[/tex]Hope this helps you

Drag the tiles to the correct boxes to complete the pairs. Match the angle measurements in radians with equivalent measurements less than or equal to 360°.
Answer:
60° =19π/3
288°=22π/9
315°=23π/4
80°=18π/5
Step-by-step explanation:
The question is incomplete. Find the completed question in the attachment.
We are to convert the radian values to the corresponding degrees that are less than 360°
Since π rad = 180°
For 23π/4:
If π rad = 180°
23π/4 = x
Cross multiply:
πx = 23π/4 × 180
x = 23π/4π × 180
x = (23×180)/4
x = 1035°
Next is to scale down 1035° to a degree less than 360 and to do this we will be subtracting multiples of 360° from the value gotten.
x = 1035 - (360×2)
x = 1035 - 720
x = 315°
Hence 23π/4 = 315°
For 18π/5:
If π rad = 180°
18π/5 = y
Cross multiply:
πy = 18π/5 × 180
y = 18π/5π × 180
y = (18×180)/5
y = 648°
In scaling down:
y = 648°-360°
y = 288°
Hence 18π/5 = 288°
For 22π/9:
If π rad = 180°
22π/9 = t
Cross multiply:
πt = 22π/9 × 180
t = 22π/9π × 180
t = (22×180)/9
t = 440°
In scaling down:
t = 440-360°
t = 80°
Hence 22π/9 = 80°
For 19π/3:
If π rad = 180°
19π/3 = y
Cross multiply:
πy = 19π/3 × 180
y = 19π/3π × 180
y = (19×180)/3
y = 3420/3
y = 1140°
In scaling down:
y = 1140°-(3×360)°
y = 1140-1080
y = 60°
Hence 19π/3 = 60°
Answer:
the other person was almost right except they mixed up 2 of them. this is the right answer, i hope this helps :)
60° =19π/3
288°=18π/5
315°=23π/4
80°=22π/9
have a great day :))
