Question

$\frac{y}{2} - 3x$

Answer 1

$\frac{y}{2} - 3x$

= (y - 6x )/2 .

Finding roots of y-6x/2

Take x = 0 , then y - 6(0)/2 = 0 then y = 0 .

Take x = 1 , then y-6/2 = 0 then y = 6 .

Take x = a then y - 6a/2 =0 then y = 6a .

Take y = b then b-6x= 0 then x = b/6

Any ordered pair of the form ( a, 6a ) or (b/6 , b) would be a solution for y/2 - 3x
