Question

write the equation of two lines passing through (3,5) one of which is parallel to y+5=0 and other is perpendicular to it

Answer 1

y

=-5 is the line .

..

so perpendicular to it will be parallel to y axis and pass through 3,5. so equation is x

=3

..

parallel line will be parallel to y axis and pass through 3,5.. so equation is y

=5
