## anonymous one year ago What is the distance between points P(10, 7) and Q(1, 8)?

In the form of a radical.

use formula D*D=(x2-x1)^2+(y2-y1)^2 and (x1,y1)=(10,7) so on take root since D*D in LHS

Isn't that the formula for midpoint?

distance between two points $$(x_1,y_1)$$ and $$(x_2,y_2)$$ is given by $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ which is really the Pythagorean theorem in disguise :-)
