Draw the graph of equation `x/(4) + y/(5) = 1` Use the graph drawn to find:
(i) x1, the value of x, when y = 10
(ii) y1, the value of y, when x = 8.

उत्तर
First, prepare a table as follows:
| X | -1 | 0 | 1 |
| Y | `(25)/(4)` | 5 | `(15)/(4)` |
The graph of the equation can be drawn as follows:
From the graph, it can be verified that:
for y = 10, the value of x = - 4.
for x = 8 the value of y = - 5.
