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}`
