Write the point-slope form of the equation of the line through the given point and slope. through: (1, -2), slope = -6
y - 2 = -6 (x + 1)
y - 2 = 6 (X + 1)
y + 2 = -6 (x - 1)
y + 2 = 6 (x - 1)

Step-by-step explanation:

Given

Determine the point slope equation

This can be determined using the following formula:

Where:

So, we have:

This gives:

Hence, the point slope form is

so what is the problem what are they asking you to solve

step-by-step explanation:

so what is the problem what are they asking you to solve

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
