Question
For every point P (x, y, z) on the x-axis (except the origin),
Options
x = 0, y = 0, z ≠ 0
x = 0, z = 0, y ≠ 0
y = 0, z = 0, x ≠ 0
x = y = z = 0

Solution
y=0, z = 0, x ≠ 0
Both Y and Z coordinates on each point of the x−axis are equal to zero. The X−coordinate on the origin is also equal to zero.Therefore, the Y and Z coordinates on each point of the x−axis, except the origin, are equal to zero, while the X−coord
