Find the distance between the points (0, 0) and (6, -8).
4
√28
10

10, imagine a line going through those 2 points. make that point into a hypotenuse of a right triangle. The length of the triangle is 6 and the height is 8 because the 6-0=6 (x values) and -8-0=-8 (y values). so use pythagorean theorem

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
