Question

4. x=2, y=-1 is a solution of the linear
equation.

(a) x+2y=0
(b) x+2y=4

(c) 2x+y=0 (d) s 2x+y=5​

Answer 1

Answer:

what is s in d part bro in the ques

if it's a typo then b and d are correct

Answer 2

Answer:

a) x+2y = 0

In this we have make either x dependent on y or y depending on x.

x=-2y

For y = 0, x= 0

For y = 1, x= -2

For y = 2, x= -4

Solutions for this equation are (0,0)(-2,1)(-4,2)

Similarly solve other questions.

x=4-2y

For y = 0, x= 4

For y = 1, x= 2

For y = 2 , x= 0

Solutions for this equation are (4,0)(2,1)(0,2)
