The direct variation equation relates x and y is y =
x
Step-by-step explanation:
Direct variation is when one variable is equal to a constant times another variable
If y varies directly with x, then
- y ∝ x
- y = k x is the equation of variation
- k is the constant of variation
∵ y varies directly with x
∵ y ∝ x
∴ y = k x
∵ y = 10 when x = 3
- Substitute these values in the equation above to find k
∴ 10 = k(3)
∴ 10 = 3 k
- Divide both sides by 3
∴ k = 
∴ The equation of variation is y =
x
The direct variation equation relates x and y is y =
x

This is the answer
first you must eliminate the denominator and that you do with multiplication
then eliminate the number that is on the same side of the letter and that you do it by placing the same number but with a different sign and so you have the answer.
also there is the check.
