A student who waits on tables at a restaurant recorded the cost of meals and the tip left by single diners. The tip left can be modeled by T(c)=0.16c+0.02, where c is the cost of the meal. Identify and explain the meanings of the slope and y-intercept in the context of this problem in a way the student's manager and coworkers would understand.

1. The slope is_________

• 16
• 0.16
• 0.02
• -0.02
• the tip when the cost of the meal is $0
• the tip for every $1 increase in the cost of the meal
• the cost of the meal for every $1 increase in tip
• the cost of the meal when the tip is $0

1. The slope represents___________

• 16
• 0.16
• 0.02
• -0.02
• the tip when the cost of the meal is $0
• the tip for every $1 increase in the cost of the meal
• the cost of the meal for every $1 increase in tip
• the cost of the meal when the tip is $0

1. The y-intercept is________

• 16
• 0.16
• 0.02
• -0.02
• the tip when the cost of the meal is $0
• the tip for every $1 increase in the cost of the meal
• the cost of the meal for every $1 increase in tip
• the cost of the meal when the tip is $0

1. The y-intercept represents____________

• 16
• 0.16
• 0.02
• -0.02
• the tip when the cost of the meal is $0
• the tip for every $1 increase in the cost of the meal
• the cost of the meal for every $1 increase in tip
• the cost of the meal when the tip is $0
