Question

Y and x vary directly. If the constant of variation is 1/2, then what is the value of y when x= -6

Answer 1

If x=-6, then y=-3

Further explanation:

Direct proportion means that if a quanitity increases the other quantity also increases and vice versa

The direct proportion is written as:

If y and x vary directly then

y∝x

y=kx

where k is the proportionality constant

If k=1/2 then the expression will be:

$y=\frac{1}{2}x\\Putting\ x=-6\\y=\frac{1}{2}* (-6)\\y=-3$

If x=-6, then y=-3
