Question

Find the slope of the line passing through the point (-6,7) and (-6,-8).

Answer 1

The gradient/slope is undefined.

using the gradient formula,
`m=(y2-y1)/(x2-x1)`,

`(-8-7)/(-6-(-6))`

try solving this and you'll get the answer "math error". this is because -6-(-6) is -6+6, which equals 0. anything divided by zero is infinite.
