Question

Find all solutions
5x+2y=0
7x+3y=0

Answer 1

I'm guessing you mean isolating your y?

Answer 2

noppe find all possible answers for x and y

Answer 3

You can't?

Answer 4

All possible cordinates that works for the above

Answer 5

Oh...

Answer 6

I only got (0,0)

Answer 7

Use table of values, makes it easier.

Answer 8

haha nah you should use algebra

Answer 9

It ends up to the same thing anyways.

Answer 10

I'll do one.

5x+2y=0
2y = -5x
y = -2.5x

If x is 1 then

y = -2.5(1)
y=-2.5

(1,-2.5)

If x is 2 then

y =-2.5(2)
y=-5

(2,-5)

Answer 11

Two coordinates for this line so you can draw it.

Answer 12

Don't forget about the other line, 7x + 3y = 0

Answer 13

That is so wrong

Answer 14

This is a university question by the way

Answer 15

Jake, I know. I was onlydoing one so he could do the other.

Answer 16

oh, good catch... sorry to interrupt :)

Answer 17

Haha, join in. He seems to disagree.

Answer 18

your solution is so bullpellet lol

Answer 19

Vanc, ALL possible coordinates... There would be many.

Answer 20

Copy down the exact question.

Answer 21

nah there are only 2

Answer 22

it is a system

Answer 23

I know.

Answer 24

a cordinate that would work for both at the same time

Answer 25

Now you say it x_x

Answer 26

That is what a system is

Answer 27

\[y _{1} = y _{2}\]

Answer 28

Whew . . . what is going on here?

Answer 29

Math.

Answer 30

5x+2y=0
7x+3y=0

Solve the first equation for x, solve the second equation for y and substitute one into the other.

Answer 31

(or use elimination, or matrices, or graphing, or . . .)
