#### 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"#
