The slopes of the two lines are 3, 3.
The slope of AB is 3.
What is the slope of a line passing through two points?
The slope of a line passing through points [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] is
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Given two points are [tex]A(-1, -4)[/tex] and [tex]B(2, 5)[/tex].
Therefore, the slope of a line passing through those two points is
[tex]m_{1} = \frac{5 - (-4)}{2-(-1)}[/tex]
⇒ [tex]m_{1} = \frac{9}{3}[/tex]
⇒ [tex]m_{1} = 3[/tex]
Another two points are [tex]C(3, -7)[/tex] and [tex]D(5, -1)[/tex].
[tex]m_{2} = \frac{-1 - (-7)}{5-3}[/tex]
⇒ [tex]m_{2} = \frac{6}{2}[/tex]
⇒ [tex]m_{2} = 3[/tex]
