Question

Find the slope of the line that goes through: (-1, -12) and (9, 68)

Answer 1

Answer:

The slope of the line is 8.

Step-by-step explanation:

The points on the straight line are:

A = (-1, -12)

B = (9, 68)

Compute the slope of the line as follows:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

   $=\frac{68-(-12)}{9-(-1)}\\\\=\frac{68+12}{9+1}\\\\=\frac{80}{10}\\\\=8$

Thus, the slope of the line is 8.
