To find the slope, we have to choose to points
[tex]\begin{gathered} \text{Slope}=\frac{y_2-y_1}{x_2-x_1} \\ _{} \end{gathered}[/tex]
[tex]\begin{gathered} x_1=40 \\ x_2=50 \\ y_1=50 \\ y_2=100 \end{gathered}[/tex]
Substitute into the formula
[tex]\begin{gathered} \text{Slope =}\frac{100-50}{50-40} \\ \\ \text{Slope}=\frac{50}{10} \\ \\ \text{Slope =5} \end{gathered}[/tex]
The final answer is
Slope = 5
