Solving for 'y'

2x - 2y + 5 = 0

Add 2y on both sides

2x + 5 = 2y

Divide by 2 on both sides

y = x + 5/2
y = x + 2.5

Solving for 'x'

2x - 2y + 5 = 0

Subtract 2x on both sides.

-2y + 5 = -2x

Divide 2x on both sides

x = y - 5/2
x = y - 2.5

If you are trying to graph it, then you need to simplify it to simplest linear slope form: y = mx + b

As of now, you have 2x - 2y + 5 = 0

Isolate the y to one side of the equation, -2y = -2x - 5

Divide the entire equation by -2, to completely isolate the y,
y = x + 5/2

Basically, y = x + 5/2 and x = y - 5/2

Consider the sequence given by a plus 8 pattern: 2, 10, 18, 26, ….
Finger [1]

Answer:

n = 1 second formula

n = 0 first formula

Step-by-step explanation:

I answer this in the other question you put, here it is again.

This is easy to get. We know the sequence cause it follows a pattern of 8, so let's try some values of n from 1 to 4, to get those numbers with the first formula:

n = 1,2,3,4

f(1) = 8(1) + 2 = 10

f(2) = 8(2) + 2 = 18

f(3) = 8(3) + 2 = 26

f(4) = 8(4) + 2 = 34

As you can see, with the first formula, the first term is 10, and not 2. The only way to get 2 with n = 1 is with the second formula:

f(1) = 8(1) - 6 = 2

f(2) = 8(2) - 6 = 10

f(3) = 8(3) - 6 = 18

f(4) = 8(4) - 6 = 26

With n = 1, the second formula was better and correct.

The first formula could be right only beggining with n = 0. Here is the proof:

f(0) = 8(0) + 2 = 2
