Question

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

Answer 1

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.

I've attached a picture just in case you were still confused :)

Hope this helps :)
