Question

PLEASE HELP WAITED 1 HR FOR HELP! :(

PB has endpoints at -2 and 12. What is the coordinate of its midpoint?
(Whoever explains, can you please show steps so I can fully understand? Thanks!)

Answer 1

wait.....a point does not have a midpoint

Answer 2

Again, what is PB?

Answer 3

It is what my homework says :/

Answer 4

What's your subject/theme?

Answer 5

Geometry

Answer 6

a line has to have two endpoint coordinates

Answer 7

This is exactly what it says.

PB has endpoints at -2 and 12. What is the coordinate of its midpoint?

Answer 8

Exactly, what acxbox says, so I guess this line just goes along the x-axis ;)
A line that goes from -2 to 12 is 12+2=14 in length, divide that by 2 and you have the center point ;)

Answer 9

no like two coordinates like
(2,0) and (5,4)

Answer 10

\[12 + 2 = 14 / 2\]
like this?

Answer 11

I have 7 then

Answer 12

@acxbox22 @Gschibby

Answer 13

you found the distance to the mid point (it is 7 more than -2 and also 7 less than 12)

you can find the actual mid point by doing -2 + 7

you could also find the mid point by find the average of the two end points:
(-2 + 12)/2

Answer 14

So for the actual mid point I got 5

Answer 15

yes.

Here is a picture

Answer 16

Okay I have a solution am I correct?\[M = -2 + 12/2 = 5/2 = 2.5\]

Answer 17

The coordinate of the midpoint of PB is 2.5?

Answer 18

M= (-2+12)/2 = 10/2 = 5 (not 2.5)

Answer 19

Sorry phi, but I think you are wrong here. 7 would be the right answer if the line goes along the x-axis :)

Answer 20

No, pellete, you're absolutely right! My bad! :P

Answer 21

so \[M = -2 + 12 / 2 = 10/2 = 5\]

The coordinate of the midpoint of PB is 5

Answer 22

yes

Answer 23

Oops, bad language warning...sorry about that! :P

Answer 24

Thank you for your help! Can you help me on 2 more?
