Question

Write the equation of the line which passes through (5, –2) and is parallel to x = 4.

Answer 1

so simple

Answer 2

?

Answer 3

x =5 is the answer

Answer 4

x=4 is just a vertical line passing through (4,0). So a line parallel to that must be vertical too. There's only one vertical line that goes through (5,-2), and that has to be x=5.
