Solve by graphing. Label the axes and show where the solution is located on the graph.The graph depicts a relationship between scores achieved on an unspecified standardized test and family income. Suppose the score for a test is 490 when the family income is $25,000 and is 530 when the family income is $55,000. Let x be the income and y be the score of the test. Graph the two given pairs of incomes and scores. Assume that the relationship is linear. Draw a line though the two previous points. From your graph, estimates the score if the family income is $40,000.
