Question

Find the equation of the vertical line which passes through the point (8,-9)

Answer 1

equation of vertical lines are of the form
\(\large x = c\)

where c is the x co-ordinate of any point on that line!

Answer 2

here the x co-ordinate is 8
so
c= 8

so what will bethe equation?

Answer 3

y = -9 would be my answer since x is horizontal?

Answer 4

In a vertical line,
all the points are equal distance from y axis

disctance from y axis is x co-ordinate

hence the equation of vertical line is of the the form x =c
