HELP CREATE MY GRAPH...

cookiemonster:

@Shadow @Mehek

cookiemonster:

hey guys, so i need your help on creating a graph for my assignment

Mehek:

Sure

cookiemonster:

thanks! this is what it says Graph the function using one of the following two options below. On the graph, make sure to label the intercepts. ~You may graph your equation by hand on a piece of paper and scan your work. ~You may graph your equation using graphic technology. Paste your graph below:

Mehek:

You can use desmos for graphic technology

cookiemonster:

and this is basically what ive written about my assignment so far so that you understand I would begin to graph this line by first putting appropriate numerical values on the y-axis and x-axis of my graph. For example, I know that when x is zero the y-value is huge. The y-intercept is close to 500. So, I would label my y-axis in 10 increments of 100 up to 1000. Next, I appropriately label the x-axis from 0-1000 in 10 increments 100. I would not include either the negative x or y values because it is not possible to sell negative sandwiches or wraps.The line on the graph represents the points at which the profit is $1, 470 for x amount of sandwiches sold and the corresponding y number of wraps that would have to be sold in order to reach that profit point exactly. The first point I would groph would be the y-intercept because I know, from the equation, (0,490) is the point at which the line intercepts the y-axis. The negative slope tells me that the y-values will be decreasing from the y-intercept to y being equal to zero. The -⅔ slope tells me that the y-values will decrease at a rate of 2 while the x-values increase at a rate of 3. I know this because I know slope is equal to the change in rise or fall in the y-direction over run in the x-direction.

Mehek:

What is the function?

cookiemonster:

f(x)= (-⅔)x+490. The function f(x) represents the points along the y-axis at which the profit is $1, 470 for x amount of sandwiches sold. The y-axis values are number of wraps that would have to be sold to reach that profit.

lol

cookiemonster:

so please help me guys create my graph..

cookiemonster:

okay? ::)

cookiemonster:

ummm hello? you guys there? :) @Shadow @Mehek

Mehek:

The link Shadow gave, use it to graph Just put in your function

cookiemonster:

but it doesnt work... can you please help me

cookiemonster:

?? :)

cookiemonster:

guys please

cookiemonster:

i need to finish this graph asap @Mehek @Shadow

Shadow:

Do not just straight copy and paste it in. Replace f(x) with y

Mehek:

It usually works for me if I use f(x) but sometimes it's the negative signs that don't let it work so I clear those and type them again Idk if it just happens to me

cookiemonster:

ok if it worked for you can you screenshot it and send it to me please

cookiemonster:

and shadow it still doesnt work,,, @Mehek please ss and send it to me

Mehek:

You'll have to zoom out since the y-intercept is so high

cookiemonster:

ok and how much do i have to zooom out

cookiemonster:

@Shadow can you please draw it for me? :)

Shadow:

Mehek kindly drew it for you. Just zoom out until you see the line.

\(\color{#0cbb34}{\text{Originally Posted by}}\) @cookiemonster ok and how much do i have to zooom out \(\color{#0cbb34}{\text{End of Quote}}\) at least 6 clicks, not too much ??...

cookiemonster:

@Shadow but what line???? im confused pleasew help

Shadow:

Click this link https://www.desmos.com/calculator/bsirwaaafq Zoom out until you see a red line.

cookiemonster:

yes i see the red line but like it just keeps going forever

Shadow:

Exactly. But what your question is asking "On the graph, make sure to label the intercepts." So simply put a point at the y intercept, and one at the x intercept. You can do this in Desmos by putting a point in there. Click on the slot below the written function to the left. Then type in (0, 490) for the y intercept. Then find the x intercept and type it in at at's own slot.

cookiemonster:

can you please just simply draw it out for me do i can understand better :)

Shadow:

You are not going to learn if we do everything. Hover over where it intercepts at the y and x axis, then type those points in.

cookiemonster:

i still dont understnad

Mehek:

It's not that hard to zoom out .-. https://www.desmos.com/calculator/xnjzb9kgzn here
