What We are Learning Today: • To solve linear equations by using: • Tables • Graphs • Equations
A Few Definitions: • Dependent Variable: • Which axis? • Independent Variable: • Which axis?
New Words for What We Know: • Rate of Change: • Constant:
Our Problem: • Alvin’s car rental charges $45 a day to rent a car and a one time fee of $25 for the car’s GPS. Bridget’s car rental charges $30 a day and a fee of $55 for the GPS.
Solve Using Table: What is our rate of change? What is our constant? Equation: How many days is a rental charge of $160 for Alvin’s? When is renting from Bridget’s cheaper?
Practice Time! • Zeno/Apex Worksheet • Remember the y axis is the dependent axis • Label your x and y axis with appropriate numbers • Graph the lines on the same graph • Need at least two points for each line
