Question

write the equation of a line which passes through (5,-2) and is parallel to x=4?

Answer 1

x= 5

Answer 2

Parellel to x=4 means verticle lines, same x value through out
so x=5

Answer 3

can you show mw how to do it?

Answer 4

x=4 is a straight line going up and down at where x=4. That means a parallel line would also be going straight up and down. For that up and down line to hit the point (5,-2) it would have to be at x=5

Answer 5

x-4=0 is our line..
guess a equation of parellel for line x+k=0
it passes through (5,-2)
hence 5+k=0
so k=-5

put it in our original equation x+k=0
hence answer is x-5=0
