For the first graph

A = (-5, 2)

B = (5, -4)

To calculate the slope we will use the following formula


\begin{gathered} m=(-4-2)/(5-(-5)) \\ m=(-6)/(10) \\ m=(-3)/(5) \end{gathered}

The answer would be m = -3/5

For the second graph

A = (-1, -1)

B = (3, 0)

To calculate the slope we will use the following formula


\begin{gathered} m=(0-(-1))/(3-(-1)) \\ m=(1)/(4) \\ \end{gathered}

The answer would be m = 1/4

For the third graph

In the third graph, we have a vertical slope at point x = 2

In this case the slope would be equal to infinity and the equation of the line would be equal to x = 2


m=\infty
