To find the slope when you know two points, you can use:

 

$$slope=\frac{y_2-y_1}{x_2-x_1}$$

 

And your points are written as (x1, y1) and (x2, y2

The subscripts don't really mean anything special, their just to signify the numbers.

So, you can put this in the equation, and you get your slope:

 

$$slope = \frac{-8 - 4}{2 - (-6)}$$

 

$$slope = \frac{-8 - 4}{2 + (+6)}$$

 

$$slope = \frac{-12}{8}$$

 

$$slope = \frac{-3}{2}$$

 

$$slope = -\frac{3}{2}$$
