12. What is the distance between P(–4, 3) and Q(6, 1)? Round to the nearest tenth.
can someone please explain how to do this problem please

draw horizontal and vertical lines from the two points to form a rectangle. The distance between them is just the diagonal of the rectangle. That is why the distance formula is
d = √(10^2+2^2) = √104
The distance formula is just the Pythagorean theorem value.
