Question

This grid shows the location of four points. Enter the distance, in units, between point A and point D. __________units

Answer 1

First, let's find the coordinate of A and D

A(-3, -3) and (5, -3)

We will now use the diatnce formula to find the distance AD

$|AD|=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}$

x₁=-3 y₁=-3 x₂ =5 y₂=-3

substitute the values into the

$AD=\sqrt[]{(5+3)^2+(-3+3)^2}$

$=\sqrt[]{(8)^2+0}$$=8\text{ units}$
