ANSWER
m = undefined
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:
[tex]m\text{ = }\frac{y_2-y_1}{x_2-x_1}[/tex]
where (x1, y1) = Point K (-4, -6)
(x2, y2) =Point J (-4, 3)
Therefore, the slope is:
[tex]\begin{gathered} m\text{ = }\frac{3\text{ - (-6)}}{-4\text{ -(-4)}} \\ m\text{ = }\frac{3\text{ + 6}}{-4\text{ + 4}}\text{ = }\frac{9}{0} \\ m\text{ = undefined} \end{gathered}[/tex]
This means that the line is a vertical line.
