Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-2, 3)

Point (9, 3)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(9+2)^2+(3-3)^2}$
Add/Subtract: $d = \sqrt{(11)^2+(0)^2}$
Simplify: $d = \sqrt{(11)^2}$
Simplify: $d = 11$
