these are (-4,-1) and (8,8) because

-1=-4*3/4+2

-1=-3=2

-1=-1

8=24/4+2

8=8

An advertiser goes to a printer and is charged $73 for 100 copies of one flyer and $82 for 400 copies of a similar flyer. Assumi
USPshnik [31]

Answer:

y = 0.03x + 70

Slope here represents the variation in the charges with the change in the number of flyers

Positive slope means that the cost is increasing with increase in number of flyers

Step-by-step explanation:

Given:

for 100 copies advertiser is charged = $73

For 400 copies advertiser is charged = $82

Now,

here the charge is a function of number of flyers

we have the general line equation for a linear relationship as:

y  = mx + c

here m is the slope

c is the constant

for the first case we have

y = $73

x = 100

thus,

73 = 100m + c ...........(1)

for the second case, we have

y = $82

x = 400

thus,

82 = 400m + c ...........(2)

subtracting (1) from (2)

    82 = 400m + c

- ( 73 = 100m + c )

==================

    9 = 300m + 0

or

m = 0.03

substituting the value of slope in equation (1)

73 = 100 × 0.03 + c

73 = 3 + c

or

c = 70

Hence,

the equation is y = 0.03x + 70

here y is amount charged and x are the number of flyers.

Slope here represents the variation in the charges with the change in the number of flyers

Positive slope means that the cost is increasing with increase in number of flyers

Write an equation in point-slope form of the line that passes through the point (9,0) and has a slope of m=-3 .
aksik [14]

Answer:

y =  - 3x + 27

Step-by-step explanation:

The standard form for the equation of the line is

y = mx + c

Recall that:

y = 0 \:  \:  \: x = 9 \:  \:  \: m =  - 3 \\ y = mx + c \\ 0 =  - 3(9) + c \\ 0 =  - 27+ c \\ 27 = c

Therefore the equation of the line is:

y = mx + c \\ y =  - 3x + 27
