Answer
The given equations are y = x - 2, y = 2x + 1 and y = 4.
Make a table (as given below) for the different pairs of the values of x and y:
| x | -4 | 0 | 3 |
|---|---|---|---|
| y = x - 2 | -6 | -2 | 1 |
| y = 2x + 1 | -7 | 1 | 7 |
| y = 4 | 4 | 4 | 4 |
Plot the points, from the table, on a graph paper and then draw a straight line passing through the points plotted on the graph.
