Write the equation of a line that is parallel to the line y = -8 and passes through point (-9, 0).

Y= -8 is a perfectly horizontal line with a slope of 0.  This line goes through the coordinate (every x value, -8).  In other words, every x value in the world (rational, that is) will have a y value of -8.  -8 is the y coordinate, so our new line has to go through the y coordinate of the given point (-9, 0).  The line y = 0 is parallel to the line y = -8.
