• 0

The line graphed on the coordinate grid can be used to determine the number of inches of water added to a swimming pool after different numbers of hours. Which statement best describes the slope of the graphed line?

• The water is being added at a rate of 0.42 inch per hour.

• The water is being added at a rate of 0.80 inch per hour.

• The water is being added at a rate of 2.40 inches per hour.

• The water is being added at a rate of 1.25 inches per hour.

A company sells bottles of vitamin capsules. The graph and table show the linear relationship between the cost per capsule in cents and the number of bottles ordered.

The table shows the number of gallons of gasoline in a car’s gas tank after the car has been driven x miles. When these data are graphed on a coordinate grid, the points all lie on the same line. What are the slope and y-intercept of this line?

• Slope = 1/25, y-intercept = 375

• Slope = -1/25, y-intercept = 15

• Slope = 25, y-intercept = 375

• Slope = -25, y-intercept = 15

What are the slope and the y-intercept of the graph of the linear function shown on the grid?

• Slope = 4, y-intercept = -6

• Slope = -4, y-intercept = -1.5

• Slope = -1/4, y-intercept = -1.5

• Slope = 1/4, y-intercept = -6
