#y = 10#

Explanation:

All horizontal lines have the equation # y = ....#

The y-value will stay the same, no matter what x-value is used.

The given point #(2,10)# gives us the y-value as 10.

The equation is #y = 10#

In slope/intercept form this would be #y = 0x+10#

The slope is 0, and the y -intercept is 10.
