Question

What is the distance in units from (-15, 20) to (-15, - 3) on the coordinate place

O. 17

!. 23

R. 30

V. 35

Answer 1

!.
`\displaystyle 23`

Explanation:

Use the Distance Formula:

`\displaystyle √([-x_1 + x_2]^2 + [-y_1 + y_2]^2) = D \\ \\ √([15 - 15]^2 + [-20 - 3]^2) = √(0^2 + [-23]^2) = √(0 + 529) = √(529) = 23`

Since we are talking about distance, we ONLY want the NON-NEGATIVE root.
