Question

Write the equation of the line which passes through (2, 1) and is perpendicular to x = –2.

Answer 1

x=-2 is a vertical line,
the line perpindicular to it would be a horizontal line and passes through (2,1) so its y=1

Answer 2

y=1. since x=-2 is vertical, a line that is perpendicular to it is horizontal. and the only horizontal line that goes through (2,1) is y=1

Answer 3

Thank You!

Answer 4

good
