प्रश्न
Draw the graph for the following
y = 4x – 1
उत्तर
When x = – 1, y = 4(–1) – 1 ⇒ y = – 5
When x = 0, y = 4(0) – 1 = 0 – 1 ⇒ y = – 1
When x = 2, y = 4(2) – 1 = 8 – 1 ⇒ y = 1
| x | – 1 | 0 | 2 |
| y | – 5 | –1 | 7 |
Plot the points (–1, –5) (0, –1) and (2, 7) in the graph sheet we get a straight line. At the time of printing change the direction.
