Question

How do you graph `2x + 3y = 9`?

Answer 1

See explanation.

Explanation:

`2x+3y=9`
`3y=9-2x`
`y=(9+2x)/3`

From the type of equation we see that the function will be a straight line that does not pass from the `(0,0)` point.

You then insert `2` random values for `x` `(x_1` and `x_2)` and get 2 values for `y` `(y_1` and `y_2)`

So you have `2` coordinates `(x_1,y_1), (x_2,y_2)`. You mark them as points and draw a straight line that passes through both points.
