Question

Geometry how to do distance formula of coordinate

Answer 1

D=√(x2-x1)² + (y2-y1)²

so what you do is take the two coordinates and you plug them in so lets say you have (2,3) and (5,7)

so you will take the first coordinate and plug it in where the X1 and Y1 is and the second coordinates where the X2 and X1 is just like so:
ex: D=√(5-2)² + (7-3)²

subtract those numbers

D=√(3)² + (4)²

square what you have left:

D=√9+16

add them together

D=√25

Square root it ((this can be done with a calculator)) then you will have your answer

D= 5

And thats all you have to do!
