Question

Write an equation of a line perpendicular to line AB below in slope-intercept form that passes through the point (7, 6).

Line AB is shown. A is at 0, 1. B is at negative 2, 5.

y = 0.5x + 2.5

y = 0.5x − 2.5

y = −2x + 20

y = 2x − 20

@ganeshie8 @John_ES

Answer 4

I would think it is A what do u guys think

Answer 5

Please im really behind in gemoetry

Answer 6

@hartnn

Answer 7

@phi

Answer 8

I think it might be A also... but i'm also really behind and kinda suck at geometry...

Answer 9

LOl we all suck at geometry

Answer 10

Jhon what do u think

Answer 11

ikr >.< too bad the person who invented it is already dead because by now he'd have an angry mob after him

Answer 12

The correct answer is A, as @Rhea101 said.

Answer 13

Actually he'd be really dead by now

Answer 14

Thanks

Answer 15

Lol true...

Answer 16

Thanks for the medal

Answer 17

Got a few more if u dont mind jhon

Answer 18

Write an equation of a line perpendicular to y = 1 over 4x + 4 in slope-intercept form that passes through the point (−2, 6).

y= 1 over 4x − 4

y= 1 over 4x + 6

y= −4x − 2

y= −4x + 1 over 4

Answer 19

Im thinking B

Answer 20

C, is the right answer.

Answer 21

When you put x=-2, you obtain y=6.

Answer 22

they tell you
A is (0, 1)
B is (-2, 5)

find the slope between the two points: change in y divided by change in x
change in y is 1 - 5 = -4
change in x is 0 - (-2) = +2

change in y divided by change x = -4/2 = -2

the slope of a line perpendicular to a line with slope m is -1/m
here, m = -2, and -1/m is -1/-2 = ½ or 0.5

that is the slope of your perpendicular line

Answer 23

to find a line through through the point (7, 6)
use
y - y0= m(x- x0) where (x0,y0) is (7,6) and m (here) is 0.5
we get
y - 6 = 0.5(x-7)
y - 6 = 0.5x -3.5
y = 0.5x -3.5+6
and finally
y = 0.5x +2.5
