Question
Draw the graph for the following
y = 2x
Solution
When x = −2, y = 2(−2) = −4
When x = 0, y = 2(0) = 0
When x = 2, y = 2(2) = 4
When x = 3, y = 2(3) = 6
| x | −2 | 0 | 2 | 3 |
| y | −4 | 0 | 4 | 6 |
Plot the points (−2, −4) (0, 0) (2, 4) and (3, 6) in the graph sheet we get a straight line.
