Rewriting Equations

by Samantha

How do I re-arrange x-y+2=0 to the y=mx+b so I can put it into a table of values?

Average Rating     Sep 15, 2010 Rating     Rewriting Equations by: Karin Hi Samantha, If you want to rewrite an equation from standard form (Ax +By = C) to slope intercept form (y=mx+b), you can do so by moving terms using the opposite operation. Step 1: You want your equation to read y =, so you want to get all the terms except y on one side of the equation. In this case, all you need to do is move the y term from the left to the right (by adding y to both sides): x-y+y +2 = 0 +y Then you are left with: x +2 = y You can then reverse sides so y is on the left. y = x + 2 and this is the equation in slope intercept form. Now you can complete your table of values. Hope this helps, Karin
