The y-coordinate is between -1 and -2. It is close to halfway between -1 and -2, but it is a little less than halfway.
Answer: Choice B. 
Answer:
Step-by-step explanation:
Adding two rational numbers results in a positive sum.
6x +30 -3x +6 =12x +18
3x +36 =12x +18
3x-12x = 18 -36
-9x = -18 | -1
9x =18
x= 18/9
x=2
Vertical angles are always equal. The vertical angles are the ones opposite each other. Therefore x would equal 40.
