Question

Write the equation of the line that is parallel to the line 4x - 3y = -12 and passes through the point (-3, 4).

A. Y= 4over3x + 8
B. Y= 4over3x + 3
C. Y= 3over4x + 8
D. Y= 3over4x + 3

Please help again.

Answer 1

What do you think?

Answer 2

if the lines are parallel then the slopes will be same....so get the slope from the 1st equation....and equation of line will be like y-y1 = m(x-x1) where x1, y1 are the points through which the line is passing

Answer 3

sorry that took a long time, i was on mobile but i think the answer is C.

Answer 4

cant be C...slopes are not equal

Answer 5

true

Answer 6

my first answer was B but maybe A, i'm really not sure

Answer 7

its A

Answer 8

Great thanks!
can you help with another?

Answer 9

yeah sure..

Answer 10

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

y = 3over2sx - 1

y = 3over2x + 3

y = -2over3x - 1

y = -2over3x + 3

Answer 11

I know it's not A

Answer 12

I'm leaning near the positive side but it has -6 so i can't tell.

Answer 13

is it C?

Answer 14

its C

Answer 15

if you can, can i have help with some others?

Answer 16

yep :)

Answer 17

k cool.
This one has a graph so i'll attatch it.

Select the equation of a line that is perpendicular to the line on the graph and passes through the point (3, 2).

y = 1 over 3 x + 3

y = -1 over 3x + 3

y = 3 x + 2

y = - 1 over 3 x + 2

Answer 18

would it be C or D? i'm thinking those.

Answer 19

its B

Answer 20

how did you get that?

Answer 21

coz y-2 =-1/3x +1

Answer 22

ahh ok i see.

Answer 23

Select the equation of the line that passes through the point (3, -1) and is parallel to the line on the graph.

y = -1

y = 3

y = x -1

y = 3x - 1

My answer is B y = 3. I know it's not A.

Answer 24

yep its b

Answer 25

really? great!

Answer 26

yep ;)
