Question

Can someone help me with standard form?

Answer 1

Standard Form: Ax + By = C

So I normally use the y intercept to find the standard since it's easier.

`y = 3x + 9`

First subtract 3x from both sides.

`-3x + y = 9`

You can leave the equation like this but I like taking out the negatives from the beginning variable. Divide both sides by negative one.

`3x - y = -9`

That should be your answer now.
