He conversion of square feet to square yards can be represented by direct variation. three square yards are equivalent to 27 square feet. let y represent the number of square yards and x the number of square feet. then y varies directly with x. what is the constant of variation? what is the equation representing the direct variation?
so given that 3 square yards equivalent to 27 square feet y represent nr. of square yards x ---------- nr. of square feet y varies directly with x what is the constant of variation ? given 3y = 27x => y = 9x so this is the equation representing the direct variation and the constant of variation is 9
