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=$\frac{3-0}{3.5-4.25}$ We simplify above and below the fraction bar with subtraction: m=$\frac{3}{-0.75}$ We divide the fraction: m=−4
