The equation for the x-axis is:
.
y = 0
.
You can interpret this equation in this way ... x can be any value because since there are
no x terms in this equation, whatever the value you choose for x makes no difference
in this equation. x can be any value from minus infinity to plus infinity.
.
But whatever value you choose for x the corresponding value of y is always zero.
.
So for example (-100,0) (-10,0) (0,0) (5, 0) (250, 0) are all points that satisfy the equation
.
y = 0
.
and if you plot them you will find that they all are on the x-axis.
.
Hope this helps you to understand the reason and logic behind saying that the equation
y = 0 is the equation for the x-axis.
