How do you graph the equation #3x=y#?

Well, all you have to do is to plug two values for #x# and find the values of #y# then graph the line. It will surely pass through the origin.

Explanation:

Let's say we choose the values #1# and #2# for #x#. All we will have to do is to find the corresponding values of #y#.

So, #3x=y#

For #x=1=>3(1)=y=>y=3#

For #x=2=>3(2)=y=>y=6#

You only need two points to graph a line and we already have them: #(1,3)# and #(2,6)#

Now, go ahead and draw your line using the two points.

The reason I'm saying that your line is going to pass through the origin is because if you put #x=0#, you will find #y=0#. That is the origin, which means the point #(0,0)#

You will see it when you are done plotting your points.

Hope this helps :)
