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

Note: is the first point . So this means that and .
Also, is the second point . So this means that and .

Start with the slope formula.

Plug in , , , and

Subtract from to get

Subtract from to get

Reduce

So the slope of the line that goes through the points and is

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.
