You can put this solution on YOUR website! Determine the slope of the line passing through each pair of points
(-7,6) and (5,2) (Graphing)
Step 1. The slope of the line m is given as
where for our example is x1=-7 y1=6, x2=5 and y2=2 (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.
