Find x if 

3x+4=10

x=2

100

Explain a negative slope

The rate of change is "decreasing" - the line for the equation is going downhill from left to right.

Gracie was kicking a soccer ball that was losing air pressure at a rate of 1.2 PSI per hour.  If the ball started with an air pressure of 11.6 PSi, how many hours will it take the ball to completely deflate? Round to the nearest hour

12 hours

300

Find the slope parallel to the line

3x - 4y = 10

parallel slope = 3/4

400

Parallel lines

Two lines that never cross. (Have the same slope)

Ms. Heavin has a car with a broken gas gauge.  She gets approximately 25 miles per gallon when driving on Paris Pike, and can travel 400 miles before her tank is empty. How many gallons does her gas tank hold? Write an equation modeling the relationship between miles traveled, m, and gallons of gas, g.

14 gallons

g = 400 - 25m
