Aline having a slope of 3/4 passes through the point(-8,4)
write the equation of this line

Step-by-step explanation:

line with slope of 3/4 going through the points (-8,4)

in y = mx + b form, the slope will be in the m position. And ur points are always (x,y)so x = -8 and y = 4

now sub all ur info into y = mx + b and we are gonna solve for the only thing we dont have and thats b, the y intercept

y = mx + b

4 = 3/4(-8) + b

4 = - 24/4 + b

4 = -6 + b

4 + 6 = b

10 = b

so ur equation for this line is : y = 3/4x + 10 <===

16.80 times .20= 3.36

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).
