Question

Find the distance between the points L(10, 14) and M(-8, 14).

Answer 1

Pythagorean theorem. Draw the right triangle that has the line segment LM as its hypotenuse.

Answer 2

distance formula would better suit this case.

Answer 3

@nestor18, The distance formula *is* the pythagorean theorem.

Answer 4

yea i used it but couldnt figure out how they got the last part

Answer 5

A simplification here is that both points are at the same height above the x-axis, so that can be ignored. Just find the difference between -8 and 10.

Answer 6

o ok thanks

Answer 7

i figured it that part out but how do u find the rest of it

Answer 8

It really helps to draw a picture of the situation:

Answer 9

Elementary counting or addition will solve this one.

Answer 10

Yes, I know just a different way to interpret it though. Seeing there is two coordinates and not a triangle I find it easier if he would research the distance formula by name since most people know pythagoreans theorem a^2+b^2=c^2

Answer 11

so then it would just be -18+0

Answer 12

Nestor18 suggests doing this:
\[d=\sqrt{(10 - (-8))^2+(14-14)^2}\]
I recommend this:
\[d=8+10\]

Answer 13

They are equivalent, but I'd rather just look at the picture and see that -8 is 8 units away from 0 and 10 is 10 units away from 0, so the total distance is 8+10.
Understand?

Answer 14

o ok yea do

Answer 15

i understand but whats the answer

Answer 16

?
I'm confused.

You don't know what 8+10 is?

Answer 17

nevermind

Answer 18

theres another part to it
