Question

Hello, How do I calculate the midpoint of a line if I don't know the slope?

Answer 1

You dont need the slope

Answer 2

\[\left( \frac{ x _{1}+x _{2} }{ 2 },\frac{ y _{1}+y _{2} }{ 2 }\right)\]

Answer 3

That's the midpoint, you'll have answer as (x,y).

Answer 4

Well, I think I do because the word problem is asking about someone walking up a hill. Normal midpoint of 928 feet would be 464. But the word problem refers to walking up a hill.

Answer 5

It still applies. No slope is necessary for midpoint

Answer 6

OK. This doesn't have anything to do with coordinate proof? : Joe is walking up a hill toward the top. The distance from the bottom to the top is 928 feet. How far, in feet, will he have walked when he reaches the midpoint of his walk up the hill?

Answer 7

Can you draw a diagram.

Answer 8

I've been trying. Joe starts at (0,0) and rises to (x, 928). I'm confused ...

Answer 9

do we know the angle of the slope then?

Answer 10

No angle of the slope. I could assume one but I'm sure that's not what the teacher is looking for.

Answer 11

I'm just going to put in 464 feet, I guess. Thanks.

Answer 12

you just need the end points of line to find the mid point

Answer 13

Yeah, which I don't get from the problem. Thanks. I just don't understand what it's getting at.

Answer 14

can u post the Q ??

Answer 15

Here it is: Joe is walking up a hill toward the top. The distance from the bottom to the top is 928 feet. How far, in feet, will he have walked when he reaches the midpoint of his walk up the hill? Thank you.

Answer 16

total length is given 2 you

Answer 17

mid means half

Answer 18

Yes: 464 feet but that feels like a strangely easy answer

Answer 19

C will be the midpoint of the line AB no matter what the slope of the hill is.
By similar triangles you can see E will be the midpoint of AD = (x1 + x2) / 2 and
F will be the midpoint of BD = (y1 + y2)/2

Answer 20

the line that will join bottom and top will be a straight line

Answer 21

mid point means two equal part

Answer 22

he ia at equal diatance from top and bottom both

Answer 23

Yup. OK Thanks for supporting me. Good night.

Answer 24

which means he has covered the half of the total distance

Answer 25

You are welcome.
