In your equations, do not enter 1x or -1x, just x or -x (for example: y = 1x + 3 should just be y = x + 3)
Also, do not enter a plus negative, just subtract. (for example y = 2x + -3 should just be y = 2x - 3)
Do not enter + 0. (for example y = -3x + 0 should just be y = -3x)
Finally, put the x-term first. y = 25 - 2x should be entered as y = -2x+25 (even though both are correct) Write the equation that could represent each problem situation.
