Question

find the slope of the line that passes through (1,5) and (9,8)

Answer 1

The slope of the line that passes through the points (x1, y1) and (x2, y2) is computed as follows:

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

In this case, the line passes through the points (1,5) and (9,8)​, then its slope is:

$m=\frac{8-5}{9-1}=\frac{3}{8}$
