Draw the graphs of the following linear equations:
5x - 5y = 8
उत्तर
5x - 5y = 8
⇒ 5x = 8 - 5y
⇒x = `(8 - 5y)/(5)`
Corresponding values of x and can be tabulated as follows :
| X | 1.6 | 0.6 | 2.6 |
| Y | 0 | 1 | 1 |
Plotting the points (1.6, 0), (0.6, 1) and (2.6, -1),
we get the following graph :
