Question

Find the distance between the points (-2,0), and (2,-2) Round to the nearest tenth if necessary.

Answer 1

Apply the formula:

$D=\sqrt[]{(y2-y1)^2+(x2-x1)^2}$

Where:

(x1,y1) = (-2,0)

(x2,y2)= (2,-2)

Replacing:;

$D\text{ =}\sqrt[]{(-2-0)^2+(2-(-2))^2}=\sqrt[]{(-2)^2+(4)^2}=\sqrt[]{4+16\text{ }}=\sqrt[]{20\text{ }}=4.5$

4.5
