Question

hlo friendz tell me how to solve this

Answer 1

----------------------------------------

Here is the solution:

----------------------------------------

Option A:

y = 2x - c

At the origin, x = 0

y = 2(0) - c

y = - c

Coordinate = ( 0, --c) => It does not pass through origin

Option B:

y = 2x + c

when x = 0

y = 2(0) + c

y = c

Coordinate = (0, c) => It does not pass through origin

Option C:

y = 2x

When x = 0

y = 2(0) = 0

Coordinate = (0,0) => it passes through origin

Answer: (C) y = 2x

Answer 2

Hii
Nice question

Solution :-

Condition for passing through the origin is ----
x = 0 and y = 0
Coordinates of Origin = (0,0)

Option A) y = 2x - c

When x = 0
y = 2(0) - c
y = -c

Coordinates = (0,-c)..

Doesn't pass through the origin

This option is incorrect.

Option B) y = 2x + c

When x = 0
y = 2(0) + c
y = c

Coordinates = (0,c)..

Doesn't pass through the origin

This option is incorrect.

Option C) y = 2x

When x = 0
y = 2(0)
y = 0

Coordinates = (0,0)

This equation passes through the origin as it satisfies the condition.

Hence, Option (C) is correct.

Hope this helps you.
