Question

please give me answer of all questions .

class 9 cbse, capter 4 linear equations in two variables.​

Answer 1

Answer:

just put the value in eqution

when we put (0,2) in left side of equation we get -4 which is not equal to 4( not equal to right side) .

when we put (2,0) in left side of equation we get 2 which is not equal to 4.

when we put (4,0) in left sidewe get 4 and this is equal to right side.

is this way we put all point in equations but only (4,0) gives left side equal to right side.

so (4,0) is only the solution of given equation.

Answer 2

After putting the valued if answer comes out to be zero, its a solution.
