The slope of the line joining the point (-2,-3) and (4,-1) is?

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

+m=%28y2-y1%29%2F%28x2-x1%29

where for our example is x1=-2, y1=-3, x2=4 and y2=-1 (think of slope=rise%2Frun). 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

m=%28-1-%28-3%29%29%2F%284-%28-2%29%29

m=%28-1%2B3%29%2F%284%2B2%29=2%2F6=1%2F3

Step 3. ANSWER: The slope is calculated as 1%2F3 or m=1%2F3

I hope the above steps were helpful.
