Question
Draw a graph of each of the following equations: x = -3y
Advertisements
Solution
x = -3y
When y = 1, x = -3(1) = -3
When y = 0, x = -3(0) = 0
When y = -2, x = -3(-2) = 6
| x | -3 | 0 | 6 |
| y | 1 | 0 | -2 |
Plotting the points (-3, 1), (0, 0) and (6, -2), we get a line AB as shown in the figure.
