Question

find the slope of the line that passes through (84,77) and (-2,49)

Answer 1

We can calculate the slope of two points (x1, y1) and (x2, y2) using the following formula:

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

Using the points (84, 77) and (-2, 49), we have:

$m=\frac{49-77}{-2-84}=\frac{-28}{-86}=\frac{14}{43}$

So the slope of the line is m = 14/43.
