Distance formula $$d =\sqrt{(x _{2}-x _{1})^2+(y _{2}-y _{1})^2}$$

anonymous · Answer

So what are your coordinates?

anonymous · Answer

You may want to use the distance formula. However, don't bother. Too many formulas to remember in math, right?

Draw a triangle and find the sides of it. The distance will be the hypotenuse. The Pythagorean formula, however, should be committed to memory!

Alright, so you have A and B.

A coordinates are, from the graph (given) = (-4,-2)
B coordinates = (5, 4)
