The table shows the distance a cyclist rides her bicycle over time. Is the rate of change in distance with respect to time constant? What does the rate of change represent?

B The rate of change is constant and represents a speed of 3360 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.

D The rate of change is constant and represents a speed of 4480 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.

A The rate of change is constant and represents a speed of 1120 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.

C The rate of change is constant and represents a speed of 2240 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.

1

Write y = 4/5 x + 8 in standard form using integers.

A −4x − 5y = 40

B 4x - 5y = -40

D 5x − 4y = 40

C −4x + 5y = 8

1

Will the graph of the line represented by the table intersect the graph of y = 5x + 4? Explain.

A No, because the y-intercepts are the same but the slopes are different. The lines are parallel.

B No, because the slopes are the same, but the y-intercepts are different. The lines are perpendicular.

C No, because the y-intercepts are the same but the slopes are different. The lines are perpendicular.

D No, because the slopes are the same but the y-intercepts are different. The lines are parallel.
