Question

Calculate the distance between the points G=(2, -2) and C = (9, -8) in the coordinate plane.

Give an exact answer (not a decimal approximation).

Answer 1

d=9

Explanation:

This is the distance formula:
`d=√((x2-x1)^2+(y2-y1)^2)`

`d=√((9-2)^2+(-8+2)^2)`

`d=\sqrt{7^2+(-6)^2\\`

`d=√(49+36)`

`d=√(85)`

d=9.21954445729

d=9
