Word Problems and Lines Examples Page 3

For the following situation, 

1. Decide what quantities the independent variable (x) and dependent variable (y) should represent.
2. Draw a graph of the situation.
3. Write a linear equation describing the situation.

Aunt Marjie doesn't like going outside in the cold. Seriously...she's a big baby about it. If it's -10° F she'll only stay outside for 2 minutes, but if it's 70° F she'll stay out for 2 hours. Even at 70° though, she's still complaining.

1. The amount of time Aunt Marjie will stay out depends on the temperature. x is the temperature in degrees Fahrenheit, and y is the number of minutes Aunt Marjie will stay out. (We could instead let y be the number of hours Aunt Marjie will stay out, but it's hard to graph th of an hour.)
2. 
3. or any equivalent equation.
