Answer:

Y=3x+2, Y= -3x-2

Step-by-step explanation:

If you need a consistent (parallel) line you must have very similar equations, with only positives and negatives being changed. If it's Y=3x+2, only the 2 is changed from negative to positive changing the lines position. If it's Y= -3x-2 then the X value is moved to a different coordinate and the -2 keeps the change.

Hope this helps and please critique what I've done if im wrong.

Consider the equation 2x-3(2x-1)=3-4x. solve the equation for x. for each step, identity the property used to write an equivalen
laila [671]
First, you expand it.

2x - 6x + 3 = 3 - 4x

Now, simplify.

-4x + 3 = - 4x

Cancel out the double "4x"

3 = 3

Since both side have an equal answer, there in an infinite number of answers.

Hope this helps! ☺♥
