What is an equation of the line that is parallel to y=-5x+6 and passes through the point (-4,-1)

y=-5x-21

Step-by-step explanation:

So the slope will be the same, rewrite the equation with the same slope and substitute in the coordinates. Then, solve for b.

y=mx+b

-1=-5(-4)+b

-1=20+b Subtract 20 from each side

-21=b

The equation is y=-5x-21

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

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).
