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?

  • 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
