Question

What is the slope of the line passing through the following points: `(7, 2) , (-8,-7)`?

Answer 1

I found `m=3/5`

Explanation:

The slope `m` represents the ratio of the change in `y` as `x` changes and gives you the inclination of a line; or:

`m=(Deltay)/(Deltax)=(y_2-y_1)/(x_2-x_1)=(-7-2)/(-8-7)=9/15=3/5`

So, this number tells you that every time `x` increases of one unit then `y` increases of `3/5`.
