A bit of help please with this question? http://i.imgur.com/7LwClsI.jpg?1

Answer 1

What would be the midpoint of (6,2) (-2,4) ?

Answer 2

Y=mx+b
Y=-1/4+7/2
can I have a metal

Answer 3

2,3?

Answer 4

@nelsonjedi

Answer 5

can I have a metal

Answer 6

Haha sorry @ICECREAMyummy but your answer is wrong..

Answer 7

How what grade are you in
I am I 8th

Answer 8

Correct..Now the origin is represented as (0,0) So waht is the distance from the origin to the midpoint?

Answer 9

2,3 @nelsonjedi

Answer 10

I am from Australia in Year 9 @ICECREAMyummy (this year)

Answer 11

okay sorry I am new here

Answer 12

@nelsonjedi what do I do from here?

Answer 13

Distance formula for (0,0) to (2,3)

Answer 14

m = 3/2 and then y = 3/2(x); y = 3x/2?

Answer 15

@nelsonjedi the answer says 3x-2y = 0 (do I always have to represent it in this from?)

Answer 16

*form

Answer 17

@nelsonjedi ?

Answer 18

My apologies..was disconnected. Forget about the distance formula as you are looking for the equation of the line. First you need to determine the slope of the line from the origin (0,0) to the mid point (2,3). Do you know how to determine the slope?

Answer 19

yep @nelsonjedi its 3-0/2-0 = 3/2

Answer 20

Good now the formula will be (y-y1) = m(x-x1)...m= slope and y1 and x1 you can plug in either of the points on the line (0,0) or (2,3) then solve.

Answer 21

y - 0 = 3/2(x - 0); y = 3x/2

Answer 22

So if y = 3x/2 +0....then y-3x/2 = 0 then multiply EVERYTHING BY 2 AND WHAT DO YOU GET?

Answer 23

opp sorry for the capital letters

Answer 24

3x-2y = 0

Answer 25

Do I always have to represent equations in this form?

Answer 26

because I could also say 2y=3x

Answer 27

Actually in the slope intercept formula it would be y=3/2x..you always show a y as y not as 2y.

Answer 28

ok but the answer says 2y-3x=0 but thanks :)

Answer 29

Sorry I thought you had that but I see different ..y-3x/2 + 0 times 2 is 2y-3x=0
