Question

** PLEASE HELP **

Write the equation of the line that is perpendicular to the line y = 3/2x + 4 and passes through the point (-6, 3).

A. y = 3/2x - 1

B. y = 3/2x + 3

C. y = -2/3x - 1

D. y = -2/3x + 3

Answer 1

how far did you get?

Answer 2

Im completely lost for this one

Answer 3

The slope of y = 3/2x + 4 is ????

Answer 4

0 ?

Answer 5

nope

Answer 6

hint: y = mx+b has a slope of m

Answer 7

3/2

Answer 8

yes

Answer 9

flip the fraction and flip the sign to get ______

Answer 10

what... ,_,

Answer 11

you have the fraction 3/2 right?

Answer 12

to find the perpendicular slope, you flip that fraction and you flip the sign

Answer 13

-2/3 ?

Answer 14

yes

Answer 15

now solve for b

\[\Large y = mx + b\]

\[\Large y = -\frac{2}{3}x + b\]

\[\Large 3 = -\frac{2}{3}(-6) + b\]

\[\Large b = ???\]

Answer 16

-1

Answer 17

m = -2/3
b = -1

the final answer is \[\Large y = -\frac{2}{3}x - 1\]

Answer 18

You're such a big help, thank you!!

Answer 19

you're welcome

Answer 20

Would you mind helping me with one more
?

Answer 21

sure I can help

Answer 22

Write the equation of the line that is parallel to the line 3x - y = -3 and passes through the point (4, -2).

y = -1/3x - 6

y = -1/3x - 14

y = 3x - 6

y = 3x - 14

Answer 23

First I would solve for y to get it into y = mx+b form (slope intercept form)

Answer 24

3x - y = -3

-y = -3-3x

-y = -3x-3

y = (-3x-3)/(-1)

y = 3x + 3

with me so far?

Answer 25

Im with you (:

Answer 26

The slope of y = 3x + 3 is m = 3

the slope of ANY parallel line to this given one will also have a slope of 3

any two parallel lines have equal slopes

Answer 27

y = mx + b

y = 3x + b

-2 = 3*4 + b

b = ???

Answer 28

-14

Answer 29

so your answer is y = 3x - 14

Answer 30

You're the best!
