What is the distance between (7,0) and (7,-9)
Naddika [18.5K]

Answer:

9 units

Step-by-step explanation:

You can use the distance formula, or you could recognize that since both points have the same x-coordinate, they lie on a vertical line, so the distance between them would be the absolute value of 0 and -9, which is 9.
