Question

2x-y=2 and 4x-4y=24 solve graphically​

Answer 1

EXPLANATION.

Graphically equation.

⇒ 2x - y = 2. - - - - - (1).

⇒ 4x - 4y = 24. - - - - - (2).

As we know that,

From equation (1), we get.

⇒ 2x - y = 2. - - - - - (1).

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

⇒ 2(0) - y = 2.

⇒ - y = 2.

⇒ y = - 2.

Their Co-ordinates = (0,-2).

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

⇒ 2x - (0) = 2.

⇒ 2x = 2.

⇒ x = 1.

Their Co-ordinates = (1,0).

From equation (2), we get.

⇒ 4x - 4y = 24. - - - - - (2).

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

⇒ 4(0) - 4y = 24.

⇒ - 4y = 24.

⇒ y = - 6.

Their Co-ordinates = (0,-6).

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

⇒ 4x - 4(0) = 24.

⇒ 4x = 24.

⇒ x = 6.

Their Co-ordinates = (6,0).

Both curves intersects at a point = (-4,-10).
