Question

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

Answer 1

The slope of the line is 8.

Explanation:

The points on the straight line are:

A = (-1, -12)

B = (9, 68)

Compute the slope of the line as follows:

`m=(y_(2)-y_(1))/(x_(2)-x_(1))`

`=(68-(-12))/(9-(-1))\\\\=(68+12)/(9+1)\\\\=(80)/(10)\\\\=8`

Thus, the slope of the line is 8.
