Question

What is the equation of the line perpendicular to the line y=4/9x-2 that passes through the point (4,3)?

Answer 1

To find perpendicular lines use this :
m1.m2=-1
Means for example if we have a line : y=8x+3
m2=-1/8
OK ?:)

Answer 2

@mrivera3113 :Got it ????

Answer 3

I still don't get it?

Answer 4

amm..
To have two line perpendicular if we have m(for first line ) * m(for 2th line ) = -1
Got it ?:)

Answer 5

So would it be y= -9 / 4 x+12?

Answer 6

Is it an answer for all of the question ????

Answer 7

the answer choices for the question is
y= -4 / 9 x - 2
y = 9 / 4 x + 6
y= -9 / 4 x + 12
y= -9 / 4 x - 12

Answer 8

@E.ali

Answer 9

OK !
I asked u another !
No problem !
Did u get to how find slope(m) ?

Answer 10

@mrivera3113

Answer 11

no

Answer 12

Look :
If we have this equation answer :
9 . x = -1
x= ?

Answer 13

@mrivera3113

Answer 14

slope of th required line will be -9/4 bcoz m1*m2=-1

Answer 15

the required eqn is,
(y-y1)=m(x-x1)
(y-3)=(-9/4)(x-4)
4(y-3)=-9(x-4)
4y-12=-9x+36
4y+9x=36+12
4y+9x=48

Answer 16

So it would be -9 / 4 x + 12? Sorry it took forever to reply I was at work.

Answer 17

yes the third option is the correct answer
