Question

Okay can you please check what I have so far and help me with my last question?

Answer 1

1. Change the equation into slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all of your work.
2x + 3y = 1200
2x-1200=-3y
1/3*(2x-1200)=1/3*-3y
2/3x-400=-y
-2/3x+400=y


2. Describe how you would graph this line using the slope-intercept method. Be sure to write in complete sentences.
I would put a dot on (0,400) After that I would have the slope do the rest. OR Have it go 2 points to the right and 3 to the down. (To form a triangle) Then it should be something like 3,398.

3. Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
F(x) = 2x + 1200


4. Graph the function using one of the following two options below. On the graph, make sure to label the intercepts.

Answer 2

I need help with 4 I dont really know what to do @ganeshie8

Answer 3

#1 is correct..but you should write it like y = -2/3x + 400 instead..

Answer 4

Okay ill change that what about 2?

Answer 5

For #2 you can say that you will find the y and x-intercepts and draw a line through them.

Answer 6

That all i have to say?

Answer 7

Yep, basically just any two points on the line and draw a straight line through them.

Answer 8

okay and What about 3?

Answer 9

Function notation is just replacing y with f(x).

So your equation was y = -2/3x + 400, you're gonna change it to f(x) = -2/3x + 400.

Answer 10

Okay i see. so now its the graph, How would i do this?

Answer 11

Use this site to graph it: https://www.desmos.com/calculator

Then take a printscreen, paste it into a paint program and save it. Then put it in the worksheet.

Answer 12

Okay thank you But where would the intercepts be on the graph?

Answer 13

You already have the y-intercept, it's 400.

To find the x-intercept input 0 for y in the equation.

Answer 14

So would the X intercept be 600?
