Question

The line $y=-2x$ cuts x – axis at

• A. (0, 0)
• B. (1, 2)
• C. (2, -8)
• D. (3, -6)

Answer 1

The correct option is A

(0, 0)

The given equation $y=-2x$ is of the form $y=mx$ and hence passes through origin (i.e.(0,0)). Therefore $y=-2x$ cuts x – axis at (0, 0). [and y = -2x cuts x – axis only at (0, 0), as a straight line cutting x-axis, can cut it only at one point].
