• Distance Formula:
  `d = √((x_2-x_1)^2+(y_2-y_1)^2)`

Explanation:

Step 1: Define

Point P(-10, 15)

Point T(15, 15)

Step 2: Find distance d

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

1. Substitute {DF]:
   `d = √((15+10)^2+(15-15)^2)`
2. Add/Subtract:
   `d = √((25)^2+(0)^2)`
3. Exponents:
   `d = √((25)^2)`
4. Evaluate:
   `d = 25`
