EXPLANATION.
⇒ 2x + y = 3. - - - - - (1).
⇒ x + 3y = -1. - - - - - (2).
As we know that,
From equation (1), we get.
⇒ 2x + y = 3. - - - - - (1).
Put the value of x = 0 in equation, we get.
⇒ 2(0) + y = 3.
⇒ y = 3.
Their Co-ordinates = (0,3).
Put the value of y = 0 in equation, we get.
⇒ 2x + (0) = 3.
⇒ 2y = 3.
⇒ y = 3/2.
⇒ y = 1.5.
Their Co-ordinates = (0,1.5).
From equation (2), we get.
⇒ x + 3y = -1. - - - - - (2).
Put the value of x = 0 in equation, we get.
⇒ (0) + 3y = -1.
⇒ 3y = -1.
⇒ y = -1/3.
⇒ y = 0.33.
Their Co-ordinates = (0,0.33).
Put the value of y = 0 in equation, we get.
⇒ x + 3(0) = -1.
⇒ x = -1.
Their Co-ordinates = (-1,0).
Both curves intersects at a point = (2,-1).
