Question

If point A is located at (-9,2)on the coordinate plane and point B is located at (-9,10)what is the distance between the two points?

Answer 1

Answer:

8

Step-by-step explanation:

To calculate the distance d, using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(- 9, 2) and (x₂, y₂ ) = B(- 9, 10)

d = $\sqrt{(-9+9)^2+(10-2)^2}$

   = $\sqrt{0^2+8^2}$ = $\sqrt{64}$ = 8

Answer 2

Answer:

8 units

Step-by-step explanation:

The x coordinates don't change so you just subtract 2 from 10 to get the distance.
