Answer:
y = -2x + 3
Step-by-step explanation:
Let equation of the line be y = mx + b
Since the line is perpendicular to y = 1/2x - 10,
product of the gradient of both lines = -1
therefore,
1/2 x m = -1
m = -2
since it passes through (4, -5),
sub (4, -5):
-5 = -2(4) + b
b = 3
therefore, equation of the line is y = -2x + 3

I will write the steps to find the slope and y-intercept from a graph.
Answers
Y-INTERCEPT: It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.
SLOPE:The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Answers
Answer:
1. 2,3; -2, 3
2. Both points share common values, but their absolute values for the x-value vary.
3. 2,3; 2, -3
4. Both points share common values, but their absolute values for the y-value vary.
Step-by-step explanation:
For 1, the answer is thus:
-On the graph, the original point is 2, 3.
-A reflection over the y-axis changes the x-value, so it would be -2,3.
Similar for the next chart:
-The initial point is 2,3.
-A reflection over the x-axis changes the y-value, so the reflected point would be 2, -3.
The explanation is:
Both points have similar values except with differences in the absolute value.
Hope this helps you.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the exponential function as -
f(x) = (0.5)ˣ + 4
An exponential function is of the form → f(x) = eˣ.The given function is -
f(x) = (1/2)ˣ + 4
The graph of the function is attached.
Therefore, the graph of the function given is attached at the end.

Select all equations that can result from adding these
two equations or subtracting one from the other.
equation 1: x + y = 12
equation 2: 3x - 5y = 4
(Select all that apply)
Answers
Answer:
Step-by-step explanation:
x + y = 12 ---------------(1)
3x - 5y = 4 --------------(2)
(1)*5 + (2) * 1 then,
5x + 3x = 60 + 4
8x = 64
x = 64/8
x = 8
from (1), 8 + y = 12
y = 4
apply(x,y)=(8,4) to these function.
-2x-4y = -32 no
-2x+6y=8 yes
like this
The required expression after the addition of the equations is 4x - 4y = 16, and the expression after the subtracting of the equations is -2x +6y = 8.
Given that,
To select all equations that can result from adding these two equations or subtracting one from the other.
equation 1: x + y = 12
equation 2: 3x - 5y = 4
The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.
Here,
Addition
x + y = 12
+ 3x - 5y = 4
--------------------
4x - 4y = 16
Subtraction,
x + y = 12
- (3x - 5y = 4)
--------------------
x + y = 12
- 3x + 5y = -4
---------------------
-2x + 6y = 8
Thus, the required expression after the addition of the equations is 4x - 4y = 16, and the expression after the subtracting of the equations is -2x +6y = 8.

The scatter plot shows the relationship between the number of car accidents in a month and the number of drivers attending a program on distracted driving. The equation represents the linear model for this data.
y=−0.0067x+17
What does the number 17 in the equation mean in this context?
A.The number of accidents decreases by 17 for every 100 drivers in the program.
B.For every 100 drivers in the program, there are 17 accidents per month.
C.There were 17 drivers in the program when it started.
D.There were 17 accidents per month when there were no drivers in the program.
E.There were no accidents per month when there were 17 drivers in the program.
Answers
Answer:
There were 17 accidents per month when there were no drivers in the program
Step-by-step explanation:
You can tell this by looking to the left-hand side and seeing the line begins at (0,17) meaning 0 drivers and 17 accidents. It’s basically showing the program causes fewer accidents than the starting point, which is 17!

The table shows the relationship between the number of drops of food color added to different number of cups of cake frosting:
Cups of
Frosting Drops of

Which point below shows an equivalent ratio in this situation?
A graph is shown. The title of the graph is Cake Decorating. The horizontal axis label is Frosting in cups. The horizontal axis values are 0, 10, 20, 30, 40, 50, 60. The vertical axis label is Food Color in drops. The vertical axis values are 0, 30, 60, 90, 120, 150, 180. Point C is plotted on the ordered pair 60,20, and Point M is plotted on the ordered pair 50, 150.
A. Point M, because if drops of food coloring are 50, then cups of frosting will be 150
B. Point M, because if cups of frosting are 50, then drops of food coloring will be 150
C. Point C, because if cups of frosting are 60, then drops of food coloring will be 20
D. Point C, because if drops of food coloring are 60, then cups of frosting will be 20

Which set of ordered pairs represents a function? (1 point)

B){(0, 0), (1, 2), (2, 6), (2, 8)}
C) {(0, 0), (0, 2), (2, 0), (2, 4)}
D) {(0, 2), (1, 4), (2, 6), (3, 6)}
Answers
Answer:
The very last set
{(0, 2), (1, 4), (2, 6), (3, 6)}.
The reason why is because of the vertical line test. If there are two y-coordinates on a x-coordinate then it is not a function. A function is that each x-coordinate has a y-coordinate with the x-coordinates being different.
Example is above. If you have any questions then leave a comment. Good luck!
