Question

x-2y=5
x+2y=5
solve it graphically​

Answer 1

Answer:

EXPLANATION.

Graphically equation.

⇒ x - 2y = 5  and  2x + y = 5.

As we know that,

From equation (1), we get.

⇒ x - 2y = 5.

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

⇒ (0) - 2y = 5.

⇒ - 2y = 5.

⇒ 2y = - 5.

⇒ y = -5/2.

⇒ y = -2.5.

Their Co-ordinates = (0,-2.5).

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

⇒ x - 2(0) = 5.

⇒ x = 5.

Their Co-ordinates = (5,0).

From equation (2), we get.

⇒ 2x + y = 5.

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

⇒ 2(0) + y = 5.

⇒ y = 5.

Their Co-ordinates = (0,5)

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

⇒ 2x + (0) = 5.

⇒ 2x = 5.

⇒ x = 5/2.

⇒ x = 2.5.

Their Co-ordinates = (2.5,0).

Both curves intersects at a point =
