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

Given two points on a line, use the formula below to find its slope
[tex]\begin{gathered} (x_1,y_1),(x_2,y_2) \\ \Rightarrow m=\frac{y_2-y_1_{}}{x_2-x_1} \end{gathered}[/tex]Therefore, in our case,
[tex]\begin{gathered} (-4,5),(3,3) \\ \Rightarrow m=\frac{5-3}{-4-3}=-\frac{2}{7} \\ \Rightarrow m=-\frac{2}{7} \end{gathered}[/tex]The slope is -2/7
