Question
The local ice cream shop offers a deal on Wednesdays where you can pay $4 for a plain ice cream sundae and $1 per topping you choose (with a maximum of 10 toppings). Which of the following graphs best models the cost someone could pay using this offer?

Answer 1

Cost = 4 + 1·(number of toppings). So the graph is a line with slope 1 and y‑intercept 4, restricted to 0 ≤ x ≤ 10. (Equivalently, a line segment from (0,4) to (10,14); if toppings must be whole numbers, the 11 integer points on that segment.)
