Finding Slope from Graph and Tables

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

Emily sells greeting cards. The graph models the linear relationship between the number of boxes of cards she sells and her profit. Which of these best describes the profit Emily makes from selling these cards?

• $7.50 per box

• $10.00 per box

• $4.00 per 30 boxes

• $3.00 per 4 boxes
