Best ResponseYou've already chosen the best response.3or you could use this : Distance between points (x1,y1) and (x2,y2) is \(\huge d=\sqrt{(x_1x_2)^2+(y_1y_2)^2}\)

Best ResponseYou've already chosen the best response.1Distance 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.

Best ResponseYou've already chosen the best response.1It's easy enough to see what the lengths of the legs of the triangle are, then solve for the hypotenuse.

Best ResponseYou've already chosen the best response.11 doesn't seem very reasonable for points that far apart.

Best ResponseYou've already chosen the best response.1That 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?

Best ResponseYou've already chosen the best response.0oh i just counted how long the triangle's height was on the picture you drew, and i counted 10

Best ResponseYou've already chosen the best response.1Ah, 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..
