SOLUTION:
We are to find the slope of the line that goes through points ( -3. -4) and ( -7, 16)
[tex]\begin{gathered} x_1=\text{ -3} \\ x_2\text{ = -7} \\ y_1=\text{ -4} \\ y_2=\text{ 16} \end{gathered}[/tex][tex]\text{Slope = }\frac{y_2-y_1}{x_2-x_1}[/tex][tex]\begin{gathered} \text{ Slope = }\frac{16-(-4)}{-7-(-3)} \\ \\ \text{Slope = }\frac{16+4}{-7+3} \\ \\ \text{Slope = }\frac{20}{-4} \\ \\ \text{Slope = -5} \end{gathered}[/tex]
