In the coordinate plane, line m had a slope of 1/4 and a y-intercept of (0,-3). line

y = x - 3

Step-by-step explanation:

Assuming you require the equation of the line

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = and y- intercept (0, - 3) ⇒ c = - 3

y = x - 3 ← equation of line

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).

answer: i think it is c
