Monday December 9, 2013Bell Ringer:

The Slope-Intercept form of a line is

y = mx + b

Answer the following questions

1.) What does m stand for

2.) What does b stand for

3.) What is the slope and y-intercept of this equation:

y = - ¾ x – 3


What we are learning today

What We are Learning Today:

  • To solve linear equations by using:

    • Tables

    • Graphs

    • Equations


A few definitions

A Few Definitions:

  • Dependent Variable:

  • Which axis?

  • Independent Variable:

  • Which axis?


New words for what we know

New Words for What We Know:

  • Rate of Change:

  • Constant:


Our problem

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

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?


Solve by graphing

Solve by Graphing:


Practice time

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
