\[d=\sqrt{x^2+y^2}=\sqrt{(x_1x)^2+(y_1y)^2}\] You have two points, find the change in x and change in y, and put into the formula.

it shouldn't make a difference since it's squared. But usually if you want to find the distance from B to C, your x1y1=C and xy=B

\[dist=\sqrt{(2+3)^2+(4+8)^2}=\sqrt{25+144}=\sqrt{169}=13\]

My distance formula says you subtract x 2 and x 1
