Math Slope

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
