Question

What is the equation of a line that passes through the point (2, 5) and is perpendicular to a line with a slope of -2

Answer 1

ok i get the slope is the reciprocal of -2 so its 2
y=2x +b
how do i find b......it says it can be
+4 or +5

Answer 2

use the same process as before
perpendicular lines you can find the slope
you have 2 points (x, y) and (2, 5)

Answer 3

negative reciprocal of -2 is 1/2

Answer 4

5=1/2(2)+b
like this

Answer 5

yes.

Answer 6

so its 4

Answer 7

b = 4
y = 1/2x + 4

Answer 8

y=1/2x+4

Answer 9

Awwww bless you guys.

Answer 10

ok i get the slope is the reciprocal of -2 so its 2
no the slope is -1/(-2/1) so it is -1*(-1/2) to get 1/2

Answer 11

yw.

Answer 12

What is the equation of a line that passes through the point (0, 2) and is perpendicular to a line with a slope of 3

Answer 13

so i got
y=-1/3x+2
