1. Suppose that an electricity bill functions similarly to the summer rates in M.2 but we don’t know the amounts charged per kWh and the monthly fee. Nate’s bill for 1417 kWh in June was $165.15, and it was $202.24 in July for 1828 kWh. a. Determine the slope in this situation. (Keep three places after the decimal for accuracy throughout the rest of the problem. b. What are the units for the slope? c. Show all work needed to write an equation for the bill.
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.
