The <u>Distance Formula</u> = 
A(1,1) ⇒ the first 1 is
& the second 1 is 
.
B(7,-7) ⇒ the first 7 is
& the second is -7 is 
.
Now all you have to do is SUBSTITUTE the variables into the distance formula to get:
.
After you plug that formula into your graphing calculator (or solve it manually & mentally), you should end up with the answer 10, therefore d=10.
