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

Answer:

!. $\displaystyle 23$

Step-by-step explanation:

Use the Distance Formula:

$\displaystyle \sqrt{[-x_1 + x_2]^2 + [-y_1 + y_2]^2} = D \\ \\ \sqrt{[15 - 15]^2 + [-20 - 3]^2} = \sqrt{0^2 + [-23]^2} = \sqrt{0 + 529} = \sqrt{529} = 23$

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