Question

Find the slope of the line through the pair of points. A(2, –3), P(2, 9).

Answer 1

Formula for slope: \[\frac {y _{2}-y _{1}}{x _{2}-x _{1}}\]

So plug in the points.
\[\frac {9-(-3)}{2-2}\]

Answer 2

If the slope divides by 0, that means it is undefined (meaning it is a vertical line)
