 $y=2\left(4x-3\right)$  

y-intercept of (0, 3) and x-intercept of (-2, 0)

y-intercept

x-intercept

2 common points

identical slopes

Only Function 1

Only Function 3

Both functions 1 & 3

Both functions 2 & 3

Function 2 has a greater y-intercept because 5 > 3.

Function 1 has a greater y-intercept because 5 > 3.

Function 2 has a greater y-intercept because -1/2 > -3.

Function 1 has a greater y-intercept because -1/2 > -3

Both functions have negative rates of change.

Both functions have positive rates of change.

Function 1 has a negative rate of change, while that of Function 2 is positive.

Function 1 has a positive rate of change, while that of Function 2 is negative.

The student arrives and shops at the grocery store.

The student decreases the bike speed significantly.

The student returns home.

The student rides the bike at a faster constant speed.

The jogger moves at a constant rate of 1 mile every 9 minutes during the first 9 minutes of the workout.

The jogger moves at a faster rate during the first 5

minutes of the workout than at any other time.

The jogger moves for only 19 minutes of the workout because the graph only shows a change in distance from minutes 0−7, 9−12, 14−17, and 19−25.

The jogger moves for only 19 minutes of the workout because the graph only shows a change in distance from minutes 7−9, 12−14, and 17−19.
