प्रश्न
On the same graph paper, plot the graphs of y = 2x - 1, y = 2x and y = 2x + 1 from x = - 2 to x = 4. Are the graphs (lines) drawn parallel to each other?
उत्तर
First, prepare a table as follows:
| X | -1 | 0 | 1 |
| Y = 2x - 1 | -3 | -1 | 1 |
| Y = 2x | -2 | 0 | 2 |
| Y = 2x + 1 | -1 | 1 | 3 |
Now the graph can be drawn as follows:
The lines are parallel to each other.
