Explanation:
#color(red)(bar(ul(|color(white)(2/2)color(black)(x=c)color(white)(2/2)|))#
#"is the equation of a vertical line parallel to the y-axis"#
#"passing through all points in the plane with an"#
#"x-coordinate of c"#
#1/2x-9=0" is in this form"#
#"add 9 to both sides and multiply by 2"#
#rArr1/2x=9rArrx=18#
#"since it is a vertical line, slope is undefined"#
#"it has an x-intercept of 18 but no y-intercept"#
