Question

Name the line which is represented by x = 0.

Answer 1

Y-axis ,on any point on Y-axis the value of x will be zero

Answer 2

We call the horizontal line the x-axis and the vertical line the y-axis. We let the right of the x-axis represent positive x values, while the top of the y-axis represents positive y values. The intersection point is where x = 0 and y = 0 is called the origin.
