A word for the relation between x and y in the equation y = k x is ___ variation.

For this case we have to define "y" directly with "x" when there is a constant of proportionality "k", such that:

This is known as direct variation.

On the other hand, if y varies inversely with x we have to:

This is known as inverse variation.

, direct variation

the answer is a

step-by-step explanation:

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
