Question 177649: Write the equation of the line that is parallel to 3 x+ 9 = 0
a) 3y + 9=0
b) Y=8
c) X=-20
d) 2x+ y=0
tell me how to find it the answer i already know what is
Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!

Your equation has no "y" variable, hence any value of y will satisfy the equation so long as

This means that the slope of the line is undefined, and the equation is of a vertical line.

Any line parallel to

must also be a vertical line and have an undefined slope. This would be represented by an equation in x only, such as
