Question 20360: Help - I'm a mom trying to help my son with his pre-algebra.
The Prentice Hall book says to Graph the equation.
4x + y = -3
We've been able to solve for x
by x + y = -3/4
then x = -3/4 - y
This matches up with the answer in the back of the book - it shows the graph -
but can't figure out how to solve for y.
Any help would be gratefully appreciated.
