What should larmont do to write a correct point slope equation for this line? (-8,5) and (-5,7)

ANSWER

Therefore the correct answer is B

EXPLANATION

The equation in the point slope form of a straight line is given by the formula;

, where is the slope and the point is any point on the line.

Since two points on the line are given, Lamont must find the slope using the points and as follows;

.

He can now choose one of the points as .

If he uses  , the he obtains,

Which gives as the equation of the line.

Therefore the correct answer is B

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
