m=−$\frac{22}{455}$
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=$\frac{3-5.2}{3.25-(-42.25)}$ We simplify above and below the fraction bar with subtraction: m=−$\frac{2.2}{45.5}$ We write this as a fraction of whole numbers by multiplying by $\frac{10}{10}$: m=−$\frac{22}{455}$
