उत्तर
The point A is on the Y-axis at a distance of 7.5 units from the origin.
∴ The coordinates are (0, 7.5).
The point B is at a distance of 4 units from Y-axis and 5 units from X-axis.
∴ The coordinates of B are (4, 5).
The point C is at a distance of 7.5 units from Y-axis and 2.5 units from X-axis.
∴ The coordinates of C denotes (7.5, 2.5).
The point D lies on X-axis at a distance of 11 units from the origin.
∴ The coordinates of D are (11, 0).
The point E is at a distance of 14.5 units from Y-axis and 6.5 units from X-axis.
∴ The coordinates of E are (14.5, 6.5).
The point F is at a distance of 18 units from Y-axis and 9.5 units from X-axis.
∴ The coordinates of F are (18, 9.5).

The table given below shows the temperatures recorded on a day at different times.
Observe the table and answer the following questions.
- What is the temperature at 8 am?
- At what time is the temperature 3°C?
- During which hour did the temperature fall?
- What is the change in temperature between 7 am and 10 am?
- During which hour was there a constant temperature?
Consider this input/output table.
| Input | 1 | 2 | 4 | 5 | 7 |
| Output | 2 | 5 | 11 | 14 | 20 |
- Graph the values from the table by taking Input along horizontal axis from 0 to 8 and Output along vertical axis from 0 to 24.
- Use your graph to predict the outputs for inputs of 3 and 8.
