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

Step-by-step explanation:

Step 1: Define

Point P (-10, 15)

Point T (15, 15)

Step 2: Find distance d

1. Substitute:                    $d = \sqrt{(15+10)^2+(15-15)^2}$
2. Add/Subtract:               $d = \sqrt{(25)^2+(0)^2}$
3. Simplify:                        $d = \sqrt{(25)^2}$
4. Simplify:                        $d = 25$
