Question

I forgot how to solve for length between two points. The problem is: Let A=(-2,5) and B=(5,-2) then solve for the distance between the points.

Answer 1

The formula for distance between two points-
√(x1- x2)^2 + (y1 -y2)^2

Solve-
√(-2 -5)^2 + (5-(-2)^2
√(-7)^2 + (7)^2
√49 + 49
√98
9.89949... (the answer will be in decimal number)
