Question

equation of x axis is-
a) x=0
b) x=a
c) y=a
d) y=0
give reason

Answer 1

In the same way, the x-axis is also the line "y = 0". Then, algebraically, an x-intercept is a point on the graph where y is zero, and. a y-intercept is a point on the graph where x is zero.

Answer 2

equation of x axis is y=0 because if we plot any point on x axis then there ordinate or y co-ordinate is always 0 and same is with y axis and equation of y axis is always x=0
