(c) y ≥ |x|
y ≥ | x | ⇒ y x ≥ or y ≥ - x \(\bigg[∵|x|=\bigg\{\begin{matrix}-x,x<0\\ x,x>0 \end{matrix}\bigg\}\bigg]\)
∴ x – y ≤ 0 or y + x ≥ 0
Plotting the points for x – y = 0, we get the
points (0, 0) (1, 1) (2, 2) etc.
Plotting the points for x + y = 0, we get the
points (0, 0) (1, –1) (2, –2) etc.
∴ (c) is the required option.
