Question

What is the distance between the two points graphed below? If necessary, round your answer to two decimal places.

Answer 1

@Nurali

Answer 2

Use the distance formula:
\[d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}\]

Answer 3

d=(1--2)2+(-5-3)2=

Answer 4

@whpalmer4

Answer 5

I don't see a square root being taken there

Answer 6

it's really not very difficult to use the equation editor button at the bottom left to produce nicely formatted equations...

Answer 7

What we're doing here is just the Pythagorean theorem in disguise

Answer 8

\[d=3^{2}+-8^{2}?\]

Answer 9

No, that's incorrect on several points.

First, \[-8^2 \ne -8*-8\]\[-8^2 = -1*8^2 = -64\]

Second, you still aren't taking the necessary square root!
