The scatter plot shows the average monthly temperature, x, and a family's monthly heating cost, y, for 23 different months. (a) Write an approximate equation of the line of best fit for the data. It doesn't have to be the exact line of best fit.

(b) Using your equation from part (a), predict the monthly heating cost for a month with an average temperature of 35°F.

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

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.
