Which situation most accurately matches the graph?

• A student was jogging from school to home. She stopped to tie her shoe and take a drink from her water bottle, then continued at the same pace as before.

• A student was jogging from school to home. She walked for a while, then continued jogging.

• A sled rider was going down a hill. The hill was steep at first, then kind of flat. At the end, it was steep again.

• A car was slowing down, then contued moving at a constant rate. Finally, it slowed to a stop,

• A line with a negative slope that crosses the x-axis at a positive value.

• A line with a negative slope that crosses the x-axis at a negative value.

• A line with a positive slope that crosses the x-axis at a positive value.

• A line with a positive slope that crosses the x-axis at a negative value.

A car travels at a rate of 65 miles per hour for 5 hours. Let y be the distance, in miles, the car travels for a given amount of time, x, in hours. This situation can be modeled by a function. Write the domain of the function in set notation.

• 0 ≤ x ≤ 5

• 0 ≤ y ≤ 5

• 0 ≤ x ≤ 65

• 0 ≤ y ≤ 65

Create a recursive rule for the given table.

Remember: a_n = a_n-1 + d

• a_n = a_n-1 + 1

• a_n = a_n-1 + 6

• a_n = a_n-1 + 11

• a_n = a_n-1 + 16
