Answer
The slope of the line is $m=3$.
Work Step by Step
We are given the two points $(5,5)$ and $(3,-1)$.
Let's use the formula to find the slope m given two points:
$m=\frac{y_1-y_1}{x_2-x_1}$
Let's plug in the values into this formula:
$m=\frac{-1-5}{3-5}$
Subtract the numerator and denominator to simplify:
$m=\frac{-6}{-2}$
The slope of the line is $m=3$.
