or you could use this : Distance between points (x1,y1) and (x2,y2) is \(\huge d=\sqrt{(x_1x_2)^2+(y_1y_2)^2}\)

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.

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

1 doesn't seem very reasonable for points that far apart.

CliffSedge Group TitleBest ResponseYou've already chosen the best response.1
That seems more reasonable, but how can you be sure? What if it wasn't a multiple choice question and you had to provide an exact value, not just one rounded to the tenths' place?

oh i just counted how long the triangle's height was on the picture you drew, and i counted 10

is it right?

CliffSedge Group TitleBest ResponseYou've already chosen the best response.1
Ah, no. You have to use Pythagorean Theorem to find the hypotenuse of the right triangle. dw:1349498042456:dw Or perhaps you would have been better off using the distance formula hart provided..
