Question

The St. James Theater is one of the largest theaters in New York City, with a seating capacity of 1600. They sell two different types of tickets, pre-sale and at-the-door. This combination of seats can be represented by the equation x + y = 1600. Choose the graph that represents the possible combinations of seat sales.

Answer 1

So look at the question:

x + y =1600

Answer 2

Solve for y:

y = -x + 1600

NOTE: slope is negative.

Answer 3

mkayyy

Answer 4

-x is 800???

Answer 5

Slope is negative so from left to right.. the line should be decreasing..

Answer 6

i dont get it

Answer 7

Left one: is increasing function. or the one with POSITIVE slope.

The right one is decreasing or the one with NEGATIVE slope

Answer 8

okay

Answer 9

Moving along, the function we had:

y = -x + 1600

Answer 10

The slope is Negative.. so it should be DECREASING.

Answer 11

ahhh pkay

Answer 12

answer??

Answer 13

Find it.

Answer 14

i cant

Answer 15

What's the slope of the given line?

Answer 16

800

Answer 17

Solve for y:

y = -x + 1600

NOTE: slope is negative.

Did you forgot ::
y = mx + b?

Where m is the slope?

Answer 18

m?

Answer 19

Yup! m.
so in
y = -x + 1600
What's the slope?

Answer 20

800??

Answer 21

WHERE IN THE WORLD CAN YOU SEE 800?

Answer 22

on the thing

Answer 23

Lol. It's -1!!!!

Answer 24

okay now wjat?

Answer 25

So the slope is Negative!!
which means it will be decreasing.. like the RIGHT one:

Answer 26

okay ??

Answer 27

now what?

Answer 28

So it will be A. B or D.

Answer 29

what will be a , b , or d

Answer 30

I think you gave us 4 options. abc&d

Answer 31

okay so the answer is???

Answer 32

Now find the x and y interceots.

Answer 33

intercepts*

Answer 34

how?

Answer 35

When x intercepts make y =0

When y intercepts make x =0

Answer 36

why would i do that??

Answer 37

why you say that?

Answer 38

maybe this will help
