If k ( x ) is a linear function, where k ( 5 ) = 1 , and k ( 4 ) = 2 , determine the slope-intercept equation for k ( x ) , then find k(0). The equation of the line is: k(0) = If m ( x ) is a linear function, where m ( 2 ) = 4 , and m ( 2 ) = 0 , determine the slope-intercept equation for m ( x ) , then find m(9). The equation of the line is: m(9) =
