By your cell phone contract you pay a monthly fee plus some money for each minute you use the phone during the month. In one month you spent 250 minutes on the phone and paid $23.25. In another month you spent 390 minutes on the phone and paid $26.75. Let x be the number of minutes you talk over the phone in a month and let y be your cell phone bill for that month. Use the linear equation to model your monthly bill based on the number of minutes you talk over the phone. This linear models slope intercept equation is ? If you spent 120 minutes over the phone in a month you would pay? If in a month you paid $29.00 of cell phone bill you must spent?
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
