## anonymous one year ago if y varies directly as x and y=8 when x=4, what is the value of y when x=16? a. 32 b. 16 c. 64 d. 28

y varies directly as x so $$y \quad\alpha \quad x$$ we can take constant of proportionality as 'k' so, y =kx

2. hartnn

now y=kx when y =8, x=4 plug these in, and tell me the value of 'k'!
