suppose that the y-axis represents total cost and x axis represents the unit quantity purchased. Which price option can be represented by a linear equation of the form y=ax+b?

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
