Question

Math test tomorrow and am trying to understand how to do slope which I am so bad in, how do i solve
parallel to 2x-2y=8 through (-1,2)
and
Perpendicular to -2x+4y=6 through (3,4)

Answer 1

Put them in slope-intercept form first and then we will go from there

Answer 2

2y=2x+b

Answer 3

Now divide both sides by 2

Answer 4

y=x+8

Answer 5

Now do the second one

Answer 6

idk im just gonna skip it for now

Answer 7

Cause there is a trick to it and i forgot how to do it

Answer 8

Do you want me to just give you the answer and the trick for perpendicular lines?

Answer 9

Yes please

Answer 10

One moment. Let me make it to where I can show you how I did it and allow you to refer to it in the future

Answer 11

Here is parallel

Answer 12

Isnt -2y supposed to be positive since youre adding it to the other side

Answer 13

and -2x isnt supposed to be -

Answer 14

In which one?

Answer 15

The parallel one where its being turned into standard form

Answer 16

Yes it it because in order to move it to the other side you have to do the opposite of its sign. In this case its a positive 2x, so you would subtract 2x, resulting in it becoming -2x

Answer 17

How? you have to add 2y since its already a - and make it equal 2x , i thought you only move the y not the x

Answer 18

No, you move the x because you're trying to get it into slope-intercept. Which is y=mx+b

Answer 19

Here is perpendicular though

Answer 20

But it could be either way anyway

Answer 21

No it cannot. You're trying to find two equations in slope-intercept that are parallel and perpendicular.

Answer 22

Okey then, thank you very much for your help

Answer 23

Do you understand it? But you're welcome

Answer 24

I better or if not ill flunk my math exam tomorrow...

Answer 25

Study with the screenshots I gave you. Take different problems and try to apply them. If you need help, I'm here.

Answer 26

thank you :)

Answer 27

You're welcome :)
