Homework Help: Math - algebraish

Posted by gorden on Monday, April 9, 2007 at 8:03pm.

hey how do we convert y=mx+b to standard form?

the standard form of the equation of a straight line is usually considered to take this form
Ax + By = C, where A,B, and C are integers and A is positive.

So if your equation is in the slope-yintercept form
step 1: eliminate any fractions
step 2. "move" the x and y terms to the left, the constants to the right.
step 3: make sure the x term is positive

e.g.

y = 4/5 x -3/4
mutiply all terms by 20

20y = 16x - 15
-16x + 20 y = -15
each term times -1

16x - 20y = 15
