For each function, y varies directly with x. find each constant of variation. then find the value of y when x=-0.3

1. y=2/3 when x=0.2
2. y=4 when x=3

1- The constant of variation is

2- The constant of variation is

Explanation:

When two variables are in direct variation, this means that when one of them increases, the other increases and vice versa

A direct variation relation is represented as follows:

y = kx

where k is the constant of variation

Now, to get the constant of variation, all we have to do is substitute with the given x and y variables and solve for k

For the given problems:

1-

Therefore:

2-

Therefore:
