Question

Hi I need help with this problem. I need to calculate the range.

Answer 1

Given two points on a line, use the formula below to find its slope

`\begin{gathered} (x_1,y_1),(x_2,y_2) \\ \Rightarrow m=\frac{y_2-y_1_{}}{x_2-x_1} \end{gathered}`

Therefore, in our case,

`\begin{gathered} (-4,5),(3,3) \\ \Rightarrow m=(5-3)/(-4-3)=-(2)/(7) \\ \Rightarrow m=-(2)/(7) \end{gathered}`

The slope is -2/7
