The members of a basketball team are selling T-shirts during spirit week. The cost is $15 for the design and $2.50 to print each T-shirt. The cost, y, to print x T-shirts is y = 2.5x + 15. What is the y-intercept and slope?
The slope of 2.5 represents the cost, in dollars, per T-shirt. The y-intercept of 15 is a one-time charge, in dollars, for the design.
