Question

Check which of the following are solutions of the equation x-2y=4 and which are not:
(i) (0,2) (ii) (2,0) (iii) (4,0) (iv) (√2,4 √2) (v) (1,1)

Answer 1

Answer: only (4,0) satisfy the equation.

Step-by-step explanation:

Given equation : x - 2y = 4

x = 4 + 2y

Now simply put given points and if LHS = RHS then that point lies on the line x - 2y = 4 otherwise not lie on the line.

On putting all points

Only (4,0) is only solution

Rest are not satisfy given equation.

Thank you!

Answer 2

Only 4'0 Are satisfy

rest are not
