Question

write the equation of the horizontal line passing through the point (3,1)

Answer 1

All horizontal lines have the same y value no matter what the x value is. Therefore the equation is simply a constant.

Answer 2

The equation is y = 1 . Horizontal line does not depended from x, that's mean for any "x" "y" is always = 1 .
