What is the equation of a line that is perpendicular to 2x+y=−4 and passes through the point (2, −8)
my answer:
1/2x9
AM I CORRECT OR NO ???

i mean y=1/2x9

nope, your slope is right, but when I substituted x = 2, I got
y = (1/2)(2)  8
= 1  8
= 7
so the point does not lie on your line.
Furthermore, since the original equation was written in standard form, I think the same style of equation would be expected. 
so its y=1/2x7?

Your equation was correct.
For some reason I wrote down your equation as
y = 1/2x8 to do my calculation,
and I then carried through the calculations with my typo.
yes, it is y = (1/2)x  9 
thnk you !
