You can put this solution on YOUR website! How do I find the slope of y=(8,8) and for x=(-7,-4) I don't understand it??
---------------------------
You find the slope of a line. A straight line is determined by 2 points, given in (x,y) format.
I don't know what you mean by "y=(8,8).
Check again, make sure you enter the problem as it's written.

You can put this solution on YOUR website! I think they are giving you two points on a line and they are asking you to find the slope.

.
Two points are:
(8,8) and (-7,-4)
.
The generalized form of a slope given two points is:
m = (y1-y2)/(x1-x2)
where
m is the slope
.
If
(x1,y1) = (8,8)
and
(x2,y2) = (-7,-4)
.
then:
m = (y1-y2)/(x1-x2)
m = (8-(-4))/(8-(-7))
m = (8+4)/(8+7)
m = 12/15
m = 4/5 (this is the slope)
