Which of the following is the equation of a line in xy-plane is perpendicular to the line with equation x=2
A) x=-1/2
B) x= -2
C) y=3
D) y =-1/2x
E) y =-2x
need solution very much
@Didar177 when you plot the line x = 2 on the xy-plane, what does it look like?
From there, you should easily be able to find the line that is perpendicular to x = 2.
I’m guessing the answer is c
While you can’t use it during an SAT, a great site to explore these graphs (and many others) is Desmos
I graphed the original equation and all 5 suggested answers here:
