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\text{ points on the line} \\ \Rightarrow slope=\frac{y_2-y_1}{x_2-x_1} \end{gathered}[/tex]
Therefore, in our case,
[tex]\begin{gathered} (0,-5),(2,-2) \\ \Rightarrow slope=\frac{-2-(-5)}{2-0}=\frac{-2+5}{2}=\frac{3}{2} \end{gathered}[/tex]
The slope is equal to 3/2.
As for the graph of the function, after drawing the four points on the plane and crossing them using a line.
