Multiple Representations of Linear Relationships

Which of the following describes the relationship shown in the graph?

• Linear; the rate of change is constant; as x increases by 4 y increases by 1.
• Linear; the rate of change is constant; as x decreases by 1 y decreases by 4.
• Nonlinear; the rate of change is not constant.
• Linear; the rate of change is constant; as x increases by 1 y increases by 4.
