Analyzing Linear Functions

A school wants to rent a cotton candy machine for a fundraiser. There is a deposit to rent it plus an additional $8 per hour. The total cost to rent the machine for 5 hours is $115, Assume the relationship is linear. What is the rate of change. How much is the deposit?

• ROC: $8/1 hr; Deposit Fee: $115

• ROC 8 hours/$1 Deposit Fee: $5

• ROC $8/1 hr Deposit Fee: $75

• ROC $5/1 hr; Deposit Fee: $75

Jenny writes the equation y = 1/2x +5.
Why is she incorrect?

• The slope is -2, the equation should be
  y = -2x + 5
• The y-intercept is 4, the equation should be y = -2x + 4
• The slope is -1/2, the equation should be
   y = -1/2x + 5
• The y-intercept is -5, the equation should be y = -2x - 5

Given the equation y = 2x + 5 , where x is the number of homework questions and y is the number of minutes it takes to do all the homework, what does the y-intercept of the line mean in real world context.

• For every homework assignment, it takes 5 more minutes to complete.
• For every homework assignment, it takes 2 more minutes to complete.
• It initially takes 5 minutes to get homework out and start working.
• It initially takes 2 minutes to get homework out and start working.
