Question

Find the distance between the two points. Round to the nearest tenth if necessary. (2, 5) and (–1, –5)

Answer 1

Make a triangle, Pythagorean theorem.

Answer 2

or you could use this :
Distance between points (x1,y1) and (x2,y2) is
\(\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\)

Answer 3

Distance formula is derived from Pythagoras' Theorem, I've found it's easier for students to remember the one formula than have to memorize another one.

Answer 4

It's easy enough to see what the lengths of the legs of the triangle are, then solve for the hypotenuse.
