Question

What is the equation of the line that passes through (12, 4) and is perpendicular to the graph of y = -3 over 4x - 2?

y = 4 over 3x - 12
y = 3 over 4x - 5
y = -4 over 3x + 20
y = -3 over 4x + 13

Answer 1

first take out the slope of from the given equation
y=mx+b
always constant term in this type of equation is yur slope so here what will be the slope it is yur job to find the slope here

Answer 2

-3/4

Answer 3

and reverse it because x is in the denominator so it will become m=-4/3

Answer 4

so its C

Answer 5

our work is not done still ... @kellyconnelly

Answer 6

y = -4/3x + 20

Answer 7

here the line is perpendicular so use this condition of slope here
m1m2=-1
and m1=-4/3
(-4/3)m2=-1
m2 = 3/4

Answer 8

now u can answer the question logically that which one is correct

Answer 9

B is the correct answer

Answer 10

now use here the point slope form and get the answer which is B

Answer 11

k @kellyconnelly is it \[y = \frac{ -3 }{ 4x-2 } ......... or............ y = \frac{ -3 }{ 4x } -2....? \]

Answer 12

omg......... which one...... the first one or the second one??

Answer 13

if it is second one then A is the correct answer

Answer 14

@kellyconnelly tell me how the equation is written in yur book

Answer 15

its neither

Answer 16

its 3/4 and then an x

Answer 17

\[\frac{ 3 }{ 4 }x\]
but negative

Answer 18

@Haseeb96
@driftracer305

Answer 19

so A is the correct answer

Answer 20

@kellyconnelly just revise the method again
because in the previous i thought that it is -3/4x and x is the denomenator but i was wrong it is in the numenator

Answer 21

so here we have no need to reverse it just put the slope into the perpendicular condition and get the answer

Answer 22

\[y = -\frac{ 3 }{ 4 }x - 2\]
