​(c)**** Choose the correct graph below.

A.

0607xy

A scatter diagram has a horizontal x-axis labeled from 0 to 6 in increments of 1 and a vertical y-axis labeled from 0 to 7 in increments of 1. The following six points are plotted, listed from left to right: (1,2.6), (1,3), (4,3.4), (5,5), (6,5.4), (6,6.6). A line rising from left to right passes through the points (1,2.6) and (6,6.6). All vertical coordinates are approximate. The line passes within 2 vertical units of all plotted points.

B.

A scatter diagram has a horizontal x-axis labeled from 0 to 6 in increments of 1 and a vertical y-axis labeled from 0 to 7 in increments of 1. The following six points are plotted, listed from left to right: (1,5.4), (1,6.6), (4,5), (5,3.4), (6,2.6), (6,3). A line falling from left to right passes through the points (1,6) and (6,3). All vertical coordinates are approximate. The line passes within 1 vertical unit of all plotted points.

C.

0607xy

A scatter diagram has a horizontal x-axis labeled from 0 to 6 in increments of 1 and a vertical y-axis labeled from 0 to 7 in increments of 1. The following six points are plotted, listed from left to right: (1,1.6), (1,0.6), (4,2.2), (5,3.6), (6,4.4), (6,4). A line, rising from left to right, passes through the points (1,0) and (6, 4.6). All vertical coordinates are approximate. The line passes within 2 vertical units of all plotted points.

For part (b), it seems like you are being asked to modify the equation \( y = x + (\text{something}) \). Based on the context, you likely need to insert a numerical value into the parentheses based on the scatter plot information or the problem's requirements.

### To approach this:

You likely need to determine the slope and intercept of the line of best fit that passes through the points provided in the scatter diagram (Part (c)) or from other given data. However, since I don’t have the exact scatter plot or more detailed data, let’s consider your goal might involve calculating the slope of the line (rise over run) and adding a constant to match the equation format.

The three options provided in Part (c) involve graphs with plotted points and lines that approximate these points.

#### Let’s analyze the graph options for Part (c):

1. **Graph A** has points like \((1, 2.6)\), \((1, 3)\), \((6, 5.4)\), and others, with a line rising from left to right, passing through \((1, 2.6)\) and \((6, 6.6)\).
   - The slope here is positive since the line is rising.

2. **Graph B** has points like \((1, 5.4)\), \((6, 2.6)\), and others, with a line falling from left to right, passing through \((1, 6)\) and \((6, 3)\).
   - The slope here is negative since the line is falling.

3. **Graph C** has points like \((1, 1.6)\), \((1, 0.6)\), and others, with a line rising from left to right, passing through \((1, 0)\) and \((6, 4.6)\).
   - The slope is positive since the line is rising.

### Choosing the correct graph:
The correct graph will depend on the specific characteristics of the data you have been working with and how the line of best fit approximates those data points. If your points fit better with a positively sloped line, **Graph A** or **Graph C** may be appropriate. If your points have a negative slope, then **Graph B** would be correct.

#### Steps for calculation:
To proceed with the modification in part (b) and to choose the right graph:
- Identify the slope of the line from the given points (if they’re available).
- Check the intercept (where the line crosses the y-axis) to complete the equation.
  
For example:
If the slope of the line is \( m = 1 \), and the y-intercept is \( b = 2 \), the equation would be \( y = x + 2 \).

Let me know if you need further details on how to calculate the slope or additional information about the graph.
