Question

What is the slope of the line that goes through points ( -3 , -4) and (-7, 16)

Answer 1

We are to find the slope of the line that goes through points ( -3. -4) and ( -7, 16)

`\begin{gathered} x_1=\text{ -3} \\ x_2\text{ = -7} \\ y_1=\text{ -4} \\ y_2=\text{ 16} \end{gathered}`
`\text{Slope = }(y_2-y_1)/(x_2-x_1)`
`\begin{gathered} \text{ Slope = }(16-(-4))/(-7-(-3)) \\ \\ \text{Slope = }(16+4)/(-7+3) \\ \\ \text{Slope = }(20)/(-4) \\ \\ \text{Slope = -5} \end{gathered}`
