Question

Find the slope of the line passing through the points (-9, -3) and (7, -7).

Answer 1

-1/4

Explanation:

The formula for finding slope given any two points on the line is:

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

Which is: (-7 - (-3)) / (7 - (-9))

Plugging it into the calculator or solving it with basic math, it gives us -4 on the numerator and 16 on the denominator. Simplify, and you get -1/4.
