So, my algebra teacher sucks. We have a final tomorrow and she didn't teach us half the shit that's on it. Basically were solving systems of equations. I have a equation, 2x - y = 1. Then to make it into slope intercept form, i subtract 2x from both sides, making it -y= -2x + 1. Normally that would be graphed m= -2/1 and b=1, but what if the y is negative? Does that change anything?
Spark Notes: what happens if the y is negative in y=mx+b?
