EXPLANATION.
Equation whose graph is,
From equation (1),
⇒ p(x) = x + 2y = 5.
Put the value of x = 0 in equation, we get.
⇒ 0 + 2y = 5.
⇒ 2y = 5.
⇒ 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).
(2) = x - 2y = 5.
Put the value of x = 0 in equation, we get.
⇒ 0 - 2y = 5.
⇒ y = -2.5.
Their Co-ordinates = (0,-2.5).
Put y = 0 in equation, we get.
⇒ x - 2(0) = 5.
⇒ x = 5.
Their Co-ordinates = (5,0).
(3) = y + 2x = 5.
Put x = 0 in equation, we get.
⇒ y + 2(0) = 5.
⇒ y = 5.
Their Co-ordinates = (0,5).
Put y = 0 in equation, we get.
⇒ 0 + 2y = 5.
⇒ 2y = 5.
⇒ y = 2.5.
Their Co-ordinates = (2.5,0).
