If y equals 4 when x equals 2 find y when x equals 16?

y=4 and x=2. find y when x=16.

this is a simple ratio problem that becomes 4/2=y/16

simplifying the equation in terms of "y", becomes y= 16 x (4 / 2)

thus, y = 32


as a quick check, realizing that y is twice as big as x or y=2x, also becomes y=32
