Answer: B; -3x+3y=6
Step-by-step explanation:
When you put -3x+3y=6 and x-y=-2 in slope intercept form, you get the same equation. Which is y=x+2. Therefore the equations are graphed on the same line and share infinitely many solutions and are consistent as well as independent.

Here 
Substitute these in the distance formula.
Step 1:

Step 2 :
Using BODMAS rule, first simplify the values into the bracket.

Step 3:
Squaring the numbers.


Therefore, George's work is correct.
Option A is the correct answer.
Answer:
The scale factor is 2.
Step-by-step explanation:
Take the vertical sides of the 2 triangles.
Their length is 3 and 6 so the scale factor is 6/3 = 2.
Also we see than the horizontal lines are in the same ratio 4 : 2 = 2:1.
