Answer:
The slope of the line passing through the given points (-2,-7) and (9,-7) is m=0
Step-by-step explanation:
Given that the line passing through the points (-2,-7) and (9,-7)
To find the slope of the line passing through the points :

Let
and
be the given points (-2,-7) and (9,-7) respectively
Substitute the points in the formula 



Therefore m=0
Therefore Slope m is 0
Therefore the slope of the line passing through the given points (-2,-7) and (9,-7) is m=0
Answer: D
Step-by-step explanation: -12*3= 36x
-3/4*-12 = +9 so, D
Answer: Sample Response :Use the linear combination method.
Multiply the first equation by –2 to create opposite terms for x.
Multiply the first equation by –4 to create opposite terms for y.
Add the system of equations to eliminate a variable.
Step-by-step explanation:
In this parallelogram, angle A and B add up to 180 (they are supplementary). Set up an equation like this and solve:
3x + 4 + 143 = 180
3x + 147 = 180
3x = 33
x = 11
The measure of x is 11°.
It should be 17 because 4.25 divided by 0.25 is the same as 425/25 which is 17.
