Solve the problem.The number of family practice physicians in a certain country can be approximated by the equation 
where x is the number of years since 2010 and y is the number of physicians in thousands. Write the equation in slope-intercept form and identify the slope and y-intercept. Then, explain the meaning of the slope in this specific equation.
A. y = 
x + 54, m = 
, y-intercept is (0, 54); The slope is the amount of decrease in thousands in the number of family practice physicians in this country per year.
B. y = 
x + 540, m = 
, y-intercept is (0, 540); The slope is the amount of decrease in thousands in the number of family practice physicians in this country per year.
C. y = 
x + 540, m = 
, y-intercept is (0, 540); The slope is the amount of increase in thousands in the number of family practice physicians in this country per year.
D. y = 
x + 54, m = 
, y-intercept is (0, 54); The slope is the amount of increase in thousands in the number of family practice physicians in this country per year.
