Answer:
y is 16
Explanation:
If y varies directly as x, and y is 48 when x is 6, find the value of y when x is 2
When y varies directly as x then

where k is the constant of proportionality
y is 48 when x is 6, plug in the value and find out k


Divide both sides by 6

The equation y=kx becomes

find the value of y when x is 2

So the value of y is 16
