Chapter 3 - Section 3.4 - The Slope of a Line - Exercise Set: 13

Answer

The slope is undefined.

Work Step by Step

We can use the slope formula to calculate the slope of a line, m, that goes through two points. $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ $m=\frac{-5-1}{-1-(-1)}=\frac{-(5+1)}{-1+1}=-\frac{6}{0}$ Any number divided by 0 is undefined, so the slope is undefined.
