Which graph represents y as a function of x?
Which representation shows y as a function of x?
A relation contains the points (1, 2), (2, −1), (3, 0), (4, 1), and (5, −1).
Which statement accurately describes this relation?
The relation does not represent y as a function of x, because each value of x is associated with a single value of y.
The relation represents y as a function of x, because each value of x is associated with a single value of y.
The relation does not represent y as a function of x, because each value of y is associated with two values of x.
The relation represents y as a function of x, because one value of y is associated with two values of x.
What is the solution to the system of equations?
y = 2x + 3
y = 3x + 2

The graph models the linear relationship between the charge for a trip and the number of miles driven for two taxis.
Based on the graph, which statement appears to be true?
The charge for a trip with a distance of 5 miles cannot be determined for either Taxi 1 or Taxi 2.
The charge for a trip with a distance of 5 miles is $5 less for Taxi 1 than for Taxi 2.
The charge for a trip with a distance of 5 miles is $20 for both Taxi 1 and Taxi 2.
The charge for a trip with a distance of 5 miles is $5 greater for Taxi 1 than for Taxi 2.
