Consider the line shown in the graph with Point A $\left(0,-2\right)$(0,2) and Point B $\left(3,2\right)$(3,2)

Loading Graph...
A line is graphed in the Cartesian coordinate plane with a positive slope. This line passes through points $\left(0,-2\right)$(0,2) and $\left(3,2\right)$(3,2).
a

Find the rise (change in the $y$y value) between point A and B. Note: Ensure you have the correct sign.

b

Find the run (change in the $x$x value) between point A and B. Note: Ensure you have the correct sign.

c

Find the gradient of the line.
