Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).

Question

anonymous · Answer

@jigglypuff314 do you understand this?

jigglypuff314 · Answer

a perpendicular line has a flipped opposite slope
so first figure out what is the slope of the line given
and then take the flipped opposite of it

like if given slope = 3
then perpendicular slope = -1/3

anonymous · Answer

So, how would I figure that? Solve for x? and get Y = x?

jigglypuff314 · Answer

it's already in slope intercept form  y = mx + b
where  m = slope  :)

anonymous · Answer

OH! Okay! XD Wow.

anonymous · Answer

$$Y = 2x + 6$$
$$Y = -\frac{ 1 }{ 2 } + 3$$
$$Y = -\frac{ 1 }{ 2 } + 6$$
$$Y = 2x + 3$$

anonymous · Answer

I think A, but I'm confused. Functions are strange..

jigglypuff314 · Answer

well, what did you get as the slope for  y = 2x +2 ? :)

anonymous · Answer

2x?

jigglypuff314 · Answer

close :)
It would be just 2

now, what would be the flipped opposite of 2?

anonymous · Answer

-2

jigglypuff314 · Answer

don't forget flipped
so  -1/2   :)

now, can you make an equation out of slope = -1/2
and point (6, 3) ?

anonymous · Answer

I was about to say that! and its C! :D

jigglypuff314 · Answer

Correct! :)
