Question

5x-4y=-18?? i need help ... ill give a medal

Answer 1

are you trying to find y or x.?

Answer 2

both its a linear equation

Answer 3

Where's the other equation?

Answer 4

there isnt one i have to come up with 3 solutions for x and y and then plot it on a graph

Answer 5

Start with x = 0, x = 1, x = 2

Input those values into the equation to find the y values of each.

Answer 6

okaii soo 5*1-4y=-18 do i divide the 5*1 ??

Answer 7

No, you isolate y

Answer 8

..... ummm

Answer 9

I kept making sign mistakes

Answer 10

The correct expression for y is

\[y = \frac{5x + 18}{4}\]

Answer 11

That's about five do-overs for me.

Answer 12

my computer won't let me post the way i found answer

Answer 13

but you solve 5x - 4y = -18 for x. You get x = (4/5)y - (18/5). Substitute 0 in for y.
x= -3.6. substitute -3.6 in for x in the beginning equation. y = 0

Answer 14

If you use x = 2, x = 6, x = 10, then you should get even values for y after inputting into

\[y = \frac{5x + 18}{4}\]
