Draw the graph of 2x – 3y = 4. From the graph, find whether x = -1, y = -2 is a solution or not. (Final)
Given equation, 2x – 3y = 4
⇒ 3y = 2x-4
When x=-4, then,
⇒ y = -4
When x=-1, then,
⇒ y = -2
When x=2, then,
⇒ y = 0
When x=5, then,
⇒ y = 2
Thus we have the following table,
X | -4 | -1 | 2 | 5 |
Y | -4 | -2 | 0 | 2 |
On plotting these points we have the following graph,
Clearly, from the graph (-1, -2) is the solution of the line 2x – 3y = 4
