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

Answer:

d=9

Step-by-step explanation:

This is the distance formula: $d=\sqrt{(x2-x1)^2+(y2-y1)^2}$

$d=\sqrt{(9-2)^2+(-8+2)^2}$

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

$d=\sqrt{49+36}$

$d=\sqrt{85}$

d=9.21954445729

d=9
