Question

Finding slope of horizontal and vertical lines (The second one)

Answer 1

ANSWER

$0$

EXPLANATION

We want to find the slope of the line passing through the given points. To do this, apply the formula for the slope of a line:

$m=\frac{y_2-y_1}{x_2-x_1}$

where (x1, y1) and (x2, y2) are the two points the line passes through

Therefore, we have that the slope of the line is:

$\begin{gathered} m=\frac{-6-(-6)}{-5-4}=\frac{-6+6}{-9} \\ m=\frac{0}{9} \\ m=0 \end{gathered}$
