<u><em>Answer:</em></u>
1- The constant of variation is
2- The constant of variation is
<u><em>Explanation:</em></u>
When two variables are in direct variation, this means that when one of them increases, the other increases and vice versa
<u>A direct variation relation is represented as follows:</u>
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
<u>For the given problems:</u>
<u>1- </u>
<u>Therefore:</u>
<u>2- </u>
<u>Therefore:</u>
Hope this helps :)
