ANSWER
m = undefined
Step-by-step explanation
We have the two points K and J.
We want to find the slope.
Slope is the rate of change of the y values with respect to the x values.
The formula for slope is:
where (x1, y1) = Point K (-4, -6)
(x2, y2) =Point J (-4, 3)
Therefore, the slope is:
This means that the line is a vertical line.
