y = 5


A horizontal line is parallel to the x-axis and has a slope = 0.
The line passes through all the points in the plane with the same y-coordinate.
It's equation is #color(red)( y = c)# , where c is the value of the y-coordinates that the line passes through. In this case the line passes through 2 points, both with a y-coordinate of 5.

#rArry=5" is the equation of the line"#
