Question 986219: Hello, im in need of some help.I was given 4x+3y=6. Then I was given a table of values.
x | y
_ | 2
3 | _
_ |-1
Those numbers were some given integers, the underscores are blank spaces to fill with numbers. It says to complete the above.
I came up with 4(3)+3(-2)=6.however it then says to then graph a line defined by the points. Wouldn't this have to be in y=mx+b form? it doesn't ask to put it into that form in the book...please help ill appreciate it very much.

Your equation is not in the form y = mx + b
BUT it CAN be written in that form::
3y = -4x+6
y = (-4/3)x + 2
--------------------
If y = 2 you get -4/3 x = 0, so x = 0
That gives you the point (0,2)
If x = 3 you get (-4/3)3+2 = -2
That gives you the point (3,-2)
If y = -1 you get (-4/3)x = -3, x = 9/4
That gives you the point (9/4,-1)
---
Plot the points and draw a line thru them.
