Step-by-step explanation:

1) The restaurants were measured for each restaurant to give ratings as observations is being carried out on restaurants

2) The percentage of customers was measured to determine ratings. The food and decor can't be measured. Seating capacity is not a measurement variable.

3) The date of measurement is not mentioned

4) The measurement would have to be taken at restaurant obviously.

5) The measurments were taken to determine the ratings and decide the best restaurant

6) Since percentage of customers was measured, the customers had to be surveyed.

7) There are no categorical variables. All variables were measured on the scale of 30

8) Quantitative variable under investigation is number of customers who returned.

9) This is a survey not a design experiment. In design experiment, somethig is put on a test.

10) This is a cross-sectional data. nothing is being measurd over a period of time

11) There are no specific ocncerns since no data is mentioned in the question.

Answer:

See below.

Step-by-step explanation:

So we have the equation:

$2x+3y=1470$

To change into the slope-intercept form, we need to isolate the y-variable. Thus, subtract 2x from both sides:

$(2x+3y)-2x=(1470)-2x$

The left side cancels:

$3y=1470-2x$

Now, divide both sides by 3. The left side cancels:

$(3y)/3=(-2x+1470)/3\\y=-\frac{2}{3} x+490$

The slope-intercept form is:

$y=mx+b$

Where m is the slope and b is the y-intercept.

Thus, the slope is -2/3 and the y-intercept is 490.

So, since we already know the y-intercept is 490, plot a point at (0,490).

The slope is too small to use. Thus, multiply the fraction by 100. It is now (-200/300). This means that we move <em>down</em> 200 for every 300 (recall that the slope means rise over run. Thus, we move down 200 for every 300 to the right). Thus, another possible point would be (0+300,490-200) or (300,290). Plot that. Then, connect them.

To write in in function notation, simply substitute the y-variable for the function notation. Our independent variable here is x so we'll use that.

$y=-\frac{2}{3}x+490\\ f(x)=-\frac{2}{3}x+490$

This means that for every x sandwiches made, there is f(x) wraps made for the total sum to be $1,470.

For example, if 105 sandwiches were made, then f(105)=-2/3(105)+490=420 wraps were made for the total profit to be $1,470.

Please refer to the attached graph.

First, since the total profit has now increased, the graph above and to the right of the old graph. This is because Sal needs to sell more sandwiches and wraps. Likewise, because of this, the x- and y-intercepts will also be different. Nevertheless, if converted into the slope-intercept equation, the slope will remain the same.
