Graph the equation. This will make it easier. After graphing the points, draw a line between those 2 points. Note where they on the X and Y axis. Take those points and use the distance formula to find the length of the hypotonuse.
The distance formula is: The square root of {(y sub2 - y sub1)squared - (x sub2 - x sub1) squared}

line A (the vertical line in a right triangle) is 12 pts long (8+4=12)
Line B (the horizantal line in a right triangle) is 9 pts long (3+6=9)
Yes I know my math in the "()" looks strange but I move the triangle so the first of the 3 pts is (0,0)
SQRT(9^2+12^2)=15
The hyp. is 15
Sqrt= Square Root
