Linear Relationships

Hi Class! Make this a post on your blog titled "Linear Relationships"

Choose 3 situations below. For each situation, do the following:
-find the independent variable
-find the dependent variable
-write an equation
-describe the graph

Here is an example: Mr. Hunt eats 2 cookies per day.
Independent variable: days
Dependent variable: Cookies eaten
Equation: c=cookies eaten, d=days, so c = 2d
Graph: Starts at the origin, increases at a constant rate of 2 cookies per day.


1) Miss Slawinski shops online 3 times per day.

2) Mrs. Moseley forgets her keys 4 times per week.

3) Mr. Greig assigns atlas work 6 times a month.

4) Mrs. Domenico walks her dog 7 times a week.

5) Mr. Buchman puts $200 on his checking account and then spends $10 per day for lunch.
