Plug them into the slope formula.

$m = \dfrac{y_2-y_1}{x_2-x_1}$

$m = \dfrac{2-1}{7-7}$

igreen · Answer

Simplify

2 - 1 = ?
7 - 7 = ?

anonymous · Answer

2-1 = 1
7-7=0

anonymous · Answer

A vertical line passing through both points.

anonymous · Answer

Thank you guys! Can I ask another one with different points?

igreen · Answer

Yep, and anything divided by 0 is undefined..so the slope is undefined.

igreen · Answer

Sure, just close this and open a new one.

Ohh okay cool, thank you. An I will
