Answer:

Graph D is correct option.

Step-by-step explanation:

Given : Y+1=2 (x-1).

To find : Which of the following graphs shows the graph of this equation .

Solution : We have given that  

Equation : Y+1=2 (x-1)

Distribute 2 over (x-1)

Y+1 = 2x -2

On subtracting both sides by 1

Y = 2x -2 -1.

Y = 2x -3.

We can see the equation in form of point slope form y =  mx + b.

Where, m = slope , b is y -intercept.

Slope  = 2 and y intercept = -3.

We can see from given D graph line cut at -3 on y axis.

Therefore, Graph D is correct option.

Hi!

You can always add or subtract same value to/from both sides of equation. The same is true about multiplication and division.

In your case you have to subtract x from both sides of equation in order to get rid of it on the left side:
x+2y-x=8-x
2y=8-x

But it's easier to remember that if you want to move some member of equation to other side, you just have to change it's sign. Let's practice a bit using your equation (I have added "plus" signs where they are usually omitted to better understend what's going on):
+x+2y=+8

Move 2y to the right side:
+x=+8-2y

Move 8 to the left side:
+x+2y-8=0

Move both x and 2y to the right side:
0=8-x-2y
