Question

How do i graph y= 6 + x/3? The original equation is 3y-x=6

Answer 1

for starters u made a mistake when rearranging :|

Answer 2

great help me!

Answer 3

you didnt divide the 6 vy 3 :|

Answer 4

Your line will cross the y-axis when x = 0 (at what is called the y-intercept). You can find where that is by replacing x in your equation with 0.

i.e. y = 2 + 0/3 (zero div three is just zero, so the line crosses at y = 2)

You can find other co-ordinate points by using different values for x and evaluating y. Since you need to divide your x value by 3, it would be a good idea to use values for x that are divisible by three.

Answer 5

Wow thank you, I get what youre saying. I just didn't know exactly where to start.

Answer 6

mathdrills, could u help me next?

Answer 7

You could make a t table:

x y
0 2
3 ?
6 ?
9 ?

I left the ?, so you could fill in the blanks.

Plot those points, use a ruler to construct a line, and you will have graphed the equation.
