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"#
