Algebra One Review

The aquarium is draining a large fish tank. The pump they are using can drain 24 gallons per hour. After 3 hours, there are 78 gallons left in the tank. Write an equation in slope-intercept form to model the water left in the tank, y, after x hours of draining. How many gallons were originally in the tank?

What is the equation and slope of the line shown on the grid?

• y = 6; slope is -1

• x = 6; slope is zero

• y = 6; slope is 6

• x = 6; slope is undefined

Write the equation that best matches the graph shown.

• y = 4x

• y = 4x - 3

• y = 4/3 x + 4

• y = 4/3 x - 3

Choose the inequality that best matches the graph.
