When solving linear equations with graphs, students can make some common mistakes that can cause confusion and affect their accuracy. Let’s look at these mistakes and how to fix them.

1. Misreading the Graph: A lot of students have trouble finding the exact point where the two lines meet on the graph. If they don’t get this point right, they might come up with the wrong answers.

2. Problems with Scale: If the numbers on the graph are not lined up properly or are squished together, it can confuse students. If the scale on one side is different from the other or if one side isn’t labeled right, the graph won’t show the equations correctly.

3. Rounding Mistakes: Sometimes, when students guess where the lines meet, they round the numbers, which can lead to big mistakes. This often happens when the meeting point isn’t clearly marked on the grid.

4. Not Considering Limits: If students ignore any limits in the problem, they might accept answers that aren’t actually correct based on the equations they’re working with.

To get better at graphing and to avoid these issues, students should:

• Check their graphs by using different tools to make sure they are accurate.
• Clearly label the axes and keep the scales consistent.
• Use exact calculations whenever they can instead of just guessing.
• Look at the problem carefully to understand any limits on the domain and range of the equations.

By fixing these problems, students can improve their graphing skills and find better solutions!
