Question

Find the distance between points at (m, n-5) and (m-3, n+2).

Answer 1

distance formula same as pythagorean theorem
rephrased
square of the distance between the points = square root of{(change in vertical)^2 + (change in horizontal)^2}
vertical y1 and y2
horizontal x1 and x2
for 2 points (x1, y1) and (x2, y2)
