Question

check whether (0,2)and(2,0) are solutions of the equation x-2y=4​

Answer 1

Answer:

If we put the value of x & y =

0–2(2) = -4

-4≠4

So, the given coordinates do not lie on the graph of x-2y=4

Answer 2

Answer:

Given equation is

x-2y=4

On putting x=0&y=2 in LHS

LHS=x-2y

0-2×2= -4

-4#4

LHS #RHS

Step-by-step explanation:

The points which satisfy an equation are the solution of the equation.

x−2y=4

Putting(0,2) in the equation, 0−2×2=4⇒−4=4 which is not true.

Putting (2,0) in the equation, 2−2×0=4⇒2=4 which is not true.

Putting (4,0) in the equation, 4−2×0=4⇒4=4 which is true.

Putting ( 2,42) in the equation,

2

−2×4

2

=4⇒−7

2

=4 which is not true.

Putting (1,1) in the equation, 1−2×1=4⇒−1=4 which is not true.

Thus, the solution of an equation is (4,0).
