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=(5-13)/(24-0)=-(8)/(24)=-(1)/(3) \\ y=mx+b \\ 13=-(1)/(3)(0)+b \\ b=13 \\ y-\text{intercept}=13 \end{gathered}`
