What is standard form?
Katen [24]

Hey there! :)

When teachers ask you for the standard form in math, they are asking you to find the simplest form an equation with variables can be in.

Ax + By = C

Example : put y=2x -3 into standard form.

Subtract 2x from both sides.

-2x + y = -3 —> standard form.

Hope this helped! :)
