Solve the problem.Assume that there is a linear 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 and y be the score of the test. (a) Find the equation of the line that describes the relationship. Write your answer in slope-intercept form. (b) Use your equation from part (a) to estimate the score if the family income is $40,000.

A. (a) y = x + ; (b) 525
B. (a) y = x + ; (b) 565
C. (a) y = x + ; (b) 505
D. (a) y = 2x + ; (b) 545
