The table shows information about the number of houses with solar panels in a town. Complete the graph.
How to approach this question
1. Identify the missing data points from the table: (2020, 210), (2021, 275), (2022, 350).
2. Locate the year 2020 on the x-axis.
3. Move up to the value 210 on the y-axis and mark the point.
4. Repeat this process for the years 2021 and 2022.
5. Connect the new points to the existing line segment.
Full Answer
To complete the graph, you need to plot the points for the years 2020, 2021, and 2022 from the table.
- For 2020, the number of houses is 210. Find 2020 on the horizontal axis (Year) and 210 on the vertical axis (Number of houses) and mark the point where they meet.
- For 2021, the number is 275. Find 2021 on the x-axis and 275 on the y-axis.
- For 2022, the number is 350. Find 2022 on the x-axis and 350 on the y-axis.
After plotting these three points, connect them with line segments, continuing from the point for 2019.
Common mistakes
✗ Misreading the scale on the y-axis. Each small square represents 10 houses.
✗ Plotting points in the wrong year.
✗ Forgetting to connect the points after plotting them.
