Answer:

It is a horizontal line. The slope = 0.
The line cuts the y-axis at the point #(0,9)#

Explanation:

#y = 9# is the equation of a horizontal line. The slope is 0.

If we write it in slope-intercept form we will have:

#y = 0x +9#

This means that for any value of #x# that is chosen, the y-value is always 9 Hence #y =9#.

The y-intercept is at the point #(0,9)#
