Question

Find the distance between each pair of points. (-7, -4) and (-7, 9)

Answer 1

Answer:

$distance = \sqrt{ {( - 7 - ( - 7))}^{2} + {(9 - ( - 4))}^{2} } \\ = \sqrt{169} \\ = 13 \: units$

Answer 2

The person above is correct. The formula for distance is:
D = rad (x2-x1) squared + (y2-y1) squared
