Q2 of 35 Page 3


Draw the graph of the following equation and check whether (a) x = 2, y =5 (b) x = -1, y = 3 are solutions of
2x + 5y = 13.


5y = 13 - 2x
⇒
(Note: To draw a line any two points are enough. So let us consider any three points.)
When x = 4; y = 1
When x = -1; y = 3
When x = -6; y = 5
