It pertains to the Y= Editor.

Right now we're graphing slope intercept equations and in alot of them the slope (m in y=mx+b) is negative. So like any other calculator I hit the minus sign and then punch in the number that m equals, but when I hit enter for the equation it gives me a syntax error. Is the negative button NOT minus symbol or do I need to do something to my equation, y= editor or what?

Please let me know. I need this for tomorrow. (9/25)
