Find the slope of (-7,9) (8,3)

Step 1. The slope of the line m is given as

where for our example is x1=-7 y1=9, x2=8 and y2=3 (think of ). You can choose the points the other way around but be consistent with the x and y coordinates. You will get the same result.

Step 2. Substituting the above values in the slope equation gives

Step 3. The slope m is calculated as .

I hope the above steps were helpful.
