Question

Find the slope of the line that passes through (10,8) and (1,12)

Answer 1

1) To find out the slope, we need to plug into this formula those points:

2) So the measure of how steep is that line is given by the slope of m=-4/9

And the line has a decreasing orientation since this slope is < 0.

3) Hence, the slope is m= -4/9
