Question 781087: Hey I have a test tomorrow & I don't understand how to solve for x+3y=6
Answer by wilft1(217)   (Show Source):
You can put this solution on YOUR website! when plotting points, the easiest way is to write two columbs, one for x, the other for y, and just start substitution one or the other and solving for the other,
example
x 2-------5-------10
-----------------------------------
y 1.33,,,,0.33,,,,-1.33
i'm using dashes and commas to separate out the numbers
2+3y=6 solve for y, which will be 1.33
5+3y=6 solve again, this time it will be 0.33
10+3y=6 you do three of them so you can make sure you have a straight line when you plot them. this one equals -1.33
you can use different numbers, but if you do your math right, it will still make a straight line when you plot them
