Question

Which of the following satisfy the equation 2x-y=0 *

A) (1,2)
B) (-1,-2)
C) (2,4)
D) None​

Answer 1

Answer:

A, B ,C

(A) (1,2)

2x-y = 0

2×1-2 = 2-2 = 0

B) (-1,-2)

2x-y = 0

2×(-1)-(-2) = -2+2 = 0

C) (2,4)

2x-y = 0

2×2-4 = 0

4-4 = 0

Answer 2

Answer:

A)    B)    C)

Step-by-step explanation:

$2x-y=0\\\\if\ x=1\\2(1)-y=0\\2=y\\then\ y=2$

∴A) is correct

$2x-y=0\\\\if\ x=-1\\2(-1)-y=0\\-2=y\\then\ y=-2$

∴B) is correct

$2x-y=0\\\\if\ x=2\\2(2)-y=0\\4=y\\then\ y=4$

∴C) is correct
