You would need a point
ex: (4,5)
y=5
if its a horizontal line you just write y=(value of y on the given point)

For a horizontal line, it is y= a value
A horizontal line would be of the form y= (a number). There should be no 'x's involved in the equation.
If there is no slope in a graph, it means that the line is horizontal. A horizontal line has a slope of zero. To graph a horizontal line, you simply draw a straight line that is parallel to the x-axis. The equation of a horizontal line is typically in the form y = k, where k is a constant value.
Assuming the point is (9, -4), the equation is y = -4.
The equation of a line with an undefined slope is x = a.
