Step-by-step explanation:
Plan for store 1,
y = 47 + 20x
Here y = cost of the camera
x = number of months to pay
Plan for store 2,
y = 15x + 77
If Brianna pays off the amount in 12 months,
So for x = 12 months,
For store 1,
y = 47 + (20×12)
y = $287
For store 2,
y = 15(12) + 77
y = 180 + 77
y = $257
The camera at the second store is cheaper when he camera is paid off in 12 months because the cost at the first store is $287 and cost at the second store is $257.

Your question states: Which best models a line?
Your correct answer would be: stick.
Your answer would be stick because a stick is a perfect example of a line. A floor does not and neither a jump rope.
