Question

Which line is perpendicular to the line y = 1/2x + 2 ?

Answer 1

y=-2x

Answer 2

Slope = 1.000/2.000 = 0.500
2. x-intercept = 4/-1 = -4.00000
3. y-intercept = 4/2 = 2

My issue is that I'm not understanding how to get the accurate perpendicular line.

Answer 3

ok heres a hint for finding perpendicular lines the slope of the perpendulcar line is the negative reciprocal of the original

Answer 4

and you dont divide the slopes

Answer 5

So what you are saying is: the negative reciprocal of 1/2x + 2 is -2/1x +2?

Answer 6

it wont be +2 because the +2 is the y intercept

Answer 7

for the original line

Answer 8

well i take that back it can be

Answer 9

So if y=-2x, how do I calculate the perpendicular line? This is confusing to me.

Answer 10

y=1/2x+2
Y=-2x
See what i did and what do you mean calculate

Answer 11

Sorry, did not mean calculate, I meant find
