"perpendicular slope is undefined"

Explanation:

y=9/4-7=-19/4

y=-19/4

"is the equation of a horizontal line parallel to the x-axis"
"passing through all points in the plane with a "
"y-coordinate equal to "-19/4

"because it is a horizontal line it's slope "=0

"and so a line perpendicular to it is vertical and "
"parallel to the y-axis with slope undefined"
