Sal’s Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and The profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal’s profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold. Change the equation into slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all of your work below:

2x + 3y = 1,470 solve this for y

cookiemonster:

2x + 3y = 1,470 -2x -2x 3y/3= (-2x+1470)/3 y=(-⅔)x + 490

what do you mean copy and pasting... why did you just first assume that. im working on this assignment in a doc.. i copy and pasted it here to make sure i was correct.

looks fine then.

Vocaloid:

now find the slope and y-intercept.

3 days ago
cookiemonster:

is this it? Slope-intercept form: y=mx+b, where “m” is the slope of the line and “b” is the y-value at which the line intercepts the y-axis of the graph, the y-value when x=0. m=(-⅔) b= 490

@Vocaloid ok now following the same like problem about sarah its just a different question but i answered it and i wanted you to check if its correct

cookiemonster:

Describe how you would graph this line using the slope-intercept method. Be sure to write in complete sentences. 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.

ok great now i do need your help with the rest of the questions

cookiemonster:

i answered this one as well please check Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences. Let f(x) be equal to the number of wraps sold to reach a total profit of $1,470 for which the number of sandwiches is equal to x sandwiches. Therefore, the function notation of this equation would be 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.

ok now i need help with this: 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:

but how do i like make the graph... i have to use a graphing website?

It says you can draw it by hand and then scan it

cookiemonster:

ok.... so from what number to what number?

Again, read your directions

i have to do it from 0-1000?

Vocaloid:

That's what it says

You don't need to calculate every single value, once you have two points you can just connect them in a straight line

Vocaloid:

I would recommend graphing your x and y intercepts first

(Once you have set up your axes that is)

Need to take a break After you finish graphing, you can double check by plugging your function into wolframalpha.com

@Vocaloid ok can you atleast tell me what the function is so i can graph it

Does the slope and y-intercept match the equation?

3 days ago
cookiemonster:

well i think so the graph goes through the number 40 but then the x-axis ends at 10?

3 days ago
Vocaloid:

If the slope and y-intercept match the equation, then you should get good to go

*be good to go

right but how do i make sure that the match/

Try adding "from x = 0 to x = 1000" to the end of the function line

im so confused i literally just want to know what the graph will look like
