Describing effects of a change in slope and y-intercept
the yearly cost in dollars, y, at a video game arcade based on total game tokens purchased, x, is y = x + 60 for a member and y = x for a nonmember. explain how the graph of a nonmember’s yearly cost will differ from the graph of a member’s yearly cost.
