What are the slope and y-intercept of the graph of the given equation?

y = –4x + 2

a. the slope is –4 and the y-intercept is 2.
b. the slope is –2 and the y-intercept is –4.
c. the slope is 2 and the y-intercept is –4.
d. the slope is 4 and the y-intercept is –2.

The slope is -4 and the y-intercept is 2.

Step-by-step explanation:

Given the equation of line

As the general equation of straight line is

where m is the slope of line and c is y-intercept

Compare given equation with above equation, we get

m=-4 and c=2

Hence, the slope is -4 and y-intercept is 2

Therefore, Option A is correct.

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).
