Question

solve graphically
x-2y=2
3x-y= -4​

Answer 1

EXPLANATION.

Solve graphically.

⇒ x - 2y = 2. - - - - - (1).

⇒ 3x - y = - 4. - - - - - (2).

As we know that,

From equation (1), we get.

⇒ x - 2y = 2. - - - - - (1).

Taking y - axis. it means x = 0.

Put the value of x = 0 in the equation, we get.

⇒ (0) - 2y = 2.

⇒ - 2y = 2.

⇒ - y = 1.

⇒ y = - 1.

Their Co-ordinates = (0,-1).

Taking x - axis. it means y = 0.

Put the value of y = 0 in the equation, we get.

⇒ x - 2(0) = 2.

⇒ x = 2.

Their Co-ordinates = (2,0).

From equation (2), we get.

⇒ 3x - y = - 4. - - - - - (2).

Taking y - axis. it means x = 0.

Put the value of x = 0 in the equation, we get.

⇒ 3(0) - y = - 4.

⇒ - y = - 4.

⇒ y = 4.

Their Co-ordinates = (0,4).

Taking x - axis. it means y = 0.

Put the value of y = 0 in the equation, we get.

⇒ 3x - (0) = - 4.

⇒ 3x = - 4.

⇒ x = - 1.33.

Their Co-ordinates = (- 1.33,0).

Both curves intersects at a point = (-2,-2).
