A point on the line x + y = 0 can be represented as
(a,0)
(0,a)
(a,-a)
(a,a)
x + y = 0 ⇒ x = -y or y = -x If x = a, y = -a ∴ A point on the line x + y = 0 can be represented as (a,-a)
A point on the line x + y = 0 can be represented as (a,-a).
Any point on the line represented by x−2y=0 can be written as (2a,a).
Any point on y = x can be represented as (a,a)
Any point on the y-axis can be represented as (0,y). State whether true or false.
