Question
Draw the graph of x + y = 7
✓
Answer
To draw the graph, we need at least two solutions of the equation. You can check that x = 0, y = 7, and x = 7, y = 0 are solutions of the given equation. So, you can use the following table to draw the graph:
| x | 0 | 7 |
| y | 7 | 0 |
Draw the graph by plotting the two points from above table and then by joining the same by a line (see Fig.)
