Question

What is the equation of the line?

Answer 1

Y=0, because the y value is only 0 and the line is horizontal.

Answer 2

y = 0

Explanation:

the blue line is a horizontal line ( the x- axis ) , with equation

y = c ( c is the value of the y- coordinates the line passes through )

The y- coordinate of any point on the x- axis is zero, then

y = 0 ← equation of line
