1. if y varies directly with x, then it must have the form
y = mx , (no constant like in y = mx + b )

evaluate 11÷8 , then 22÷16, then 33÷24
Care to re-evaluate your choice ?

2. Y/X = 11/8.
Y/x = 22/16 = 11/8.
Y/X = 33/24 = 11/8.
When X was doubled, Y doubled.
When X was tripled, Y tripled.
Therefore, Y varies directly with X.
Y/X = 11/8.
8y = 11x,
Y = ?
