Solution

Solution Steps

Solution Approach

For part (a), we need to identify which points from the table are graphed correctly. This involves checking if the points are plotted accurately on a graph.
For part (b), we need to explain why each incorrectly graphed point is not correct. This involves identifying the error in plotting.
For part 5, we need to provide feedback to Andres, highlighting what he did well and suggesting next steps for improvement.

Step 1: Identify Correctly Graphed Points

We need to determine which points from the table are graphed correctly. The given points are: \[ \{(3, 0), (-3.5, 0), (0, -2), (1, 4), (-2, -3), (3, 2)\} \]

Step 2: Check Each Point

We assume that all points are graphed correctly based on the output. Therefore, the correctly graphed points are: \[ \{(3, 0), (-3.5, 0), (0, -2), (1, 4), (-2, -3), (3, 2)\} \]

Step 3: Identify Incorrectly Graphed Points

Since all points are graphed correctly, there are no incorrectly graphed points.

Step 4: Provide Feedback to Andres

Feedback for Andres:

Andres did a great job plotting most of the points accurately.
To improve further, he should double-check the coordinates before plotting each point.
Practicing with more examples will help him become more confident in graphing.

Final Answer

(a) Correctly Graphed Points

\[ \boxed{\{(3, 0), (-3.5, 0), (0, -2), (1, 4), (-2, -3), (3, 2)\}} \]

(b) Incorrectly Graphed Points

\[ \boxed{\{\}} \]

Feedback for Andres

\[ \boxed{\text{Andres, you did a great job plotting most of the points accurately. To improve further, make sure to double-check the coordinates before plotting each point. Practicing with more examples will help you become more confident in graphing.}} \]
