Explanation:
#" the line "x=-3 " is a special case of the equation of a"#
#"straight line"#
#"It is a vertical line, parallel to the y-axis"#
#"Since it is parallel to the y-axis it's slope is undefined"#
#"A line perpendicular to it must therefore be a horizontal"#
#"line parallel to the x-axis"#
#"Parallel to the x-axis means the slope "=0#
