find the equation, in function form, of athe line that passes through the points(1/2,3) and (7/6,5/9)

find slope
slope = (5/9 + 3)/(7/6  1/2)
= (32/9) / (2/3)
= (32/9)(3/2) = 16/3
so y =(16/3)x + b
sub in the "easier" of the two points, (1/2 , 3)
3 = (16/3)(1/2) + b
3 = 8/3 + b
b = 17/3
y = f(x) = (16/3)x  17/3
