6. Mrs. Henderson used 6 yards of fabric to make 3 elf costumes. What equation can
be used to model the total number of yards
of fabric y for x costumes? How many yards
of fabric do you need for 7 elf costumes?

it has the same slope and a different y-intercept

hope this : )

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
