Write an equation in slope-intercept form of the line through point p(-8, -10) with slope 4.
a. y + 10 = 4(x + 8)
b. y = 4x - 10
c. y = 4x + 22
d. y + 8 = 4(x + 10)

a

step-by-step explanation:

a

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).

the answer is d
