Solve the problem.The graph depicts a relationship between scores achieved on an unspecified standardized test and family income. Suppose the score for a test is 485 when the family income is $25,000 and is 525 when the family income is $55,000. Let x be the income, in thousands, 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. Label the axes, and show where the solution is located on the graph.
A. 
Standardized test score: 545
B. 
Standardized test score: 565
C. 
Standardized test score: 505
D. 
Standardized test score: 525
