Question

20 23 Clarisse used the ordered pairs (0.13) and (24,5) for her trend line. What would be the y-intercept of her trend line?

Answer 1

$\begin{gathered} y=mx+b \\ m=\text{slope} \\ b=y-\text{intercept} \end{gathered}$$\begin{gathered} (0,13)(24,5) \\ m=\frac{5-13}{24-0}=-\frac{8}{24}=-\frac{1}{3} \\ y=mx+b \\ 13=-\frac{1}{3}(0)+b \\ b=13 \\ y-\text{intercept}=13 \end{gathered}$
