## Algebra 1: Common Core (15th Edition)

To find the slope, we use the formula m=$\frac{y2-y1}{x2-x1}$. We plug in the x and y values from the given coordinate pairs: m=$\frac{7/13-2/11}{-2-(-2)}$ We simplify below the fraction bar with subtraction: m=$\frac{7/13-2/11}{0}$ Since any number divided by 0 is undefined, the slope of this line is undefined.
