Q1.Plot three points with first coordinate equal to (-2.8) and join them.
so, how many diagrams have you seen here?
)-2,8)
To plot three points with a first coordinate equal to (-2.8) and join them, follow these steps:
1. Take a piece of graph paper or create a virtual graph using software.
2. Along the x-axis (horizontal axis), locate the point that corresponds to the first coordinate value (-2.8). Place a dot or mark at this point.
3. Along the y-axis (vertical axis), choose three different values for the y-coordinate and mark those points as well. For example, you can choose y-coordinates like 1, -3, and 4.
4. Repeat step 3 for all three points you want to plot, using the same x-coordinate (-2.8) for each point.
5. Once you have plotted all three points, use a ruler or freehand to draw a line connecting the dots.
The resulting graph should show three points (-2.8, 1), (-2.8, -3), and (-2.8, 4) connected by a line passing through them.
