Answer:
y = 4
Step-by-step explanation:
The question is incomplete . if y = 2 when x = ? . x value is suppose to be given at that instance to get the constant of proportionality. Let us assume x was given as 1/2 or 0.5
y varies directly with x . This can be represented mathematically as follows .
y = kx
where k = constant of variation.
recall
y = 2
when = 1/2
Let us get the constant of variation k and later find y when x = 1.
y = kx
2 = 1/2 k
cross multiply
k = 4
Therefore, let us find y when x = 1
y = kx
y = 4 × 1
y = 4
In this case y is therefore equals to 4.
