What is the point slope form of a vertical line?
1 Answer
Vertical line would be parallel to y- axis, hence its equation would be x= c . The slope of vertical line is undefined, hence there is no point slope form as such. http://www.montereyinstitute.org/courses/Algebra1/COURSE_TEXT_RESOURCE/U04_L1_T1_text_final_files/image014.gif
