I'll do the first one to get you started.

Note: is the first point . So this means that x%5B1%5D=-3 and y%5B1%5D=-7.
Also, is the second point . So this means that x%5B2%5D=9 and y%5B2%5D=-7.


m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29 Start with the slope formula.


m=%28-7--7%29%2F%289--3%29 Plug in y%5B2%5D=-7, y%5B1%5D=-7, x%5B2%5D=9, and x%5B1%5D=-3


m=%280%29%2F%289--3%29 Subtract -7 from -7 to get 0


m=%280%29%2F%2812%29 Subtract -3 from 9 to get 12


m=0 Reduce


So the slope of the line that goes through the points and is m=0

Tip: Post one question at a time or else your posts will be ignored.
Slope = m
m = difference of y coordinates divided by difference of x coordinates
m = -7-(-7) divided by 9-(-3)
m = (-7 + 7)/(9 + 3)
m = 0/12
m = 0
The slope is zero. This means the line
is horizontal, which is parallel to the x-axis.
Post the other questions separately.
