Question

What steps would i use to find the distance between the points (20, -4) and (-4, 3)

Answer 1

Distance formula = sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(20,-4)...x1 = 20 and y1 = -4
(-4,3)...x2 = -4 and y2 = 3
now we sub
d = sqrt ((-4 - 20)^2 + (3 - (-4)^2)
d = sqrt ((-24^2) + (7^2))
d = sqrt (576 + 49)
d = sqrt 625
d = 25 <==
