B. relation only C. neither a relation nor a function function only D. Functions 7. Compare the and the rates of change of the following items. y-intercepts The rates of change are the same, but the are different. y-intercepts A. The items have the same and the same rate of change. y-intercept B. The are the same, but the rates of change are different. y-intercepts C. The items have different and different rates of change. y-intercepts D. Linear vs. Nonlinear 8. Which of the following best describes the equation below? = 3x2 + 6 y both linear and nonlinear A. nonlinear B. linear C. neither linear nor nonlinear D. Linear Relationships 9. Georgia filled her kitchen sink up with water so that she could do the dishes. When she was done with the dishes, she pulled out the drain stopper so the water could begin to drain out of the sink. A linear model of this situation contains the values (1, 6.8) and (3, 6.4), where represents the x number of seconds, and represents the water level in the sink, in inches. y What is the rate of change in this linear model?
