so we have y=mx+b
first we'll find the slope
if i believe, finding a line through 2 points would be point slope form.
y1-y2
--------
x1-x2
so
-7-(-7)
---------
3-(-6)
=
0
---
9
so the slope is zero
so
y=(0)x+b or y=b
substitute in any y value from your sample points: -7
so -7=b
so b=-7
so the equation is---------
y=-7
:)

As you can see, the two y-values are the same; -7.
Therefore, the line will be a horizontal line with the equation y = -7.

The line, looking at that, would be y=-7...That's the only possible way both of those x values could equal -7.

Well, Kat, it seems someone has done your homework once again for you. You will never learn anything by allowing others to do your work. How are you going to pass a test? Did you even think of that?

simple. find the slope by taking the difference in y/ difference in x. then plug one set of values in to the equation: y-y1=m(x-x1)..m is the slope.

you can't so that because Y1 - Y2 = 0.
