With a horizontal line, the y-co-ordinate never
changes no matter what is.
So, although you are given the point ( -7,-2 ),
in fact this line goes through ( x, -2 ) no matter
what you plug in for .
The slope for a horizontal line is zero, so in the
slope-intercept form, ,
so you have:

= the y-intercept which is ( 0,-2 )
( because can take any value, including )
So, is the answer
