The equation of a linear function in point-slope form is y – y1 = m(x – x1). harold correctly wrote the equation y = 3(x – 7) using a point and the slope. which point did harold use?
when harold wrote his equation, the point he used was (7, 3).
when harold wrote his equation, the point he used was (0, 7).
when harold wrote his equation, the point he used was (7, 0).
when harold wrote his equation, the point he used was (3, 7).
its not (7,0) i tried that and it was wrong

answer:   the answer is c (7, 0) is correct just took the test

we know that

the equation of the line into point-slope form is equal to

where

m is the slope

(x1,y1) is the point

in this problem we have

the slope is equal to

the point is equal to

therefore

the answer is the option

when harold wrote his equation, the point he used was

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).
