Question

What is an equation of the line that passes through the point (-4,-1) and is parallel to and perpendicular to the line 2x+7y=14 ?

Answer 1

i need help asap !

Answer 2

First, change 2x + 7y into y=mx+b form.

Answer 3

= 14*

Answer 4

how ?

Answer 5

First, move the "2x" to the other side by subtracting it to both sides, then divide by 7.

Answer 6

What do you get? y = 2/7x + 7 Now, you need to find the perpendicular, so the new line must intersect at a 90 degree angle all-around (meaning all angles to the point equal 90 to make 360).

Answer 7

Are you following this?

Answer 8

sort of...

Answer 9

Need a breakdown?

Answer 10

yea. i just really need to get the answer asap

Answer 11

If that's the case, just draw a line through the line i just gave you from the point (-4, -1)

Answer 12

but i need equations

Answer 13

Hold on, then.

Answer 14

I got y = -1 2/7x - 1/7, but i'm not sure.

Answer 15

okay.

Answer 16

Tell me if its right, kay?

Answer 17

i dont think so cause i need 2 seperate equations. one for parallel and one for perpendicular...

Answer 18

Then that would be the perpendicular. For the m, it should be 2/7x.
