Question

the equation of y axis in space is​

Answer 1

Answer:

Explanation: At any point on the y axis, only the value of y increases (as we move above the x axis) or decreases(as we go down). At all values of y, x remains constant and is equal to zero. Hence the equation of y-axis is x=0. Note: Similarly, the equation of x-axis is, y=0.

Answer 2

y axis (in space): x = 0, z = 0

Step-by-step explanation:

• In space, means, in three dimensions, so we proceed to find the equation of y-axis in three dimensions.

• We must know that, the y-axis is the intersection of xy-plane and yz-plane.

• The equation of xy-plane is z = 0 and the equation of yz-plane is x = 0.

• Thus the equations of the y-axis are x =0, z = 0.
