Question

3x - 4y = -7 ; 5x - 2y = 0 graph​

Answer 1

Step-by-step explanation:

3x+5x-4y+2y = 0

8x-2y = 0

Answer 2

EXPLANATION.

Graph of the pair of linear equation.

⇒ 3x - 4y = 7. - - - - - (1).

⇒ 5x - 2y = 0. - - - - - (2).

As we know that,

From equation (1), we get.

⇒ 3x - 4y = 7. - - - - - (1).

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

⇒ 3(0) - 4y = 7.

⇒ - 4y = 7.

⇒ 4y = - 7.

⇒ y = - 7/4.

⇒ y = - 1.75.

Their Co-ordinates = (0,-1.75).

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

⇒ 3x - 4(0) = - 7.

⇒ 3x = - 7.

⇒ x = - 7/3.

⇒ x = - 2.33.

Their Co-ordinates = (-2.33,0).

From equation (2), we get.

⇒ 5x - 2y = 0. - - - - - (2).

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

⇒ 5(0) - 2y = 0.

⇒ - 2y = 0.

⇒ y = 0.

Their Co-ordinates = (0,0).

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

⇒ 5x - 2(0) = 0.

⇒ 5x = 0.

⇒ x = 0.

Their Co-ordinates = (0,0).

Both curves intersects at a point = (1,2.5).
