Linear Relationships: constant rate of change

Pledge Plan Equations

6th Grade: M = $10

7th Grade: M = ($2) x (x)

8the Grade: M = $5 + ($.50) x (x)

Monday, April 28, 2014

There are three ways to represent a linear relationship:

- Graph
- Table
- Equation

Pledge Plans
 
Pledge 1:
$10 regardless of how far people walk 

Pledge 2:
$2 per mile regardless of how far people walk

Pledge 3:
$5 flat donation plus .50 per mile

Tell everything you know about these plans.

Dependent variable - (on the y axis) the amount of money raised because it depends on the number of miles walked
Independent variable - (on the x axis) miles because the miles don't change based on the amount of money raised

Homework: Fix the dependent and independent variables on your graph if you had them switched. Due tomorrow.

What did we learn from the Otto and Carla problem?

You can solve a problem in different ways - ratios, proportions, fractions, rate tables, unit rates, graphs, equations, constant of proportionality and percent table

Homework: Computation R corrections due Wednesday
