We see that G is three times as great as F. If F = x, then G = 3x and the distance between two consecutive tick marks is 2x.
We need to identify the point that has the coordinate –(3^12), which is the opposite of the coordinate of point G and can be denoted by –3x.
Now, we have everything in simple terms to quickly identify the point in question.
E = F – 2x = x – 2x = –x[This is not the point we are looking for.]
D = E – 2x = –x – 2x = –3x[This is the point we are looking for.]
Answer:D
but how do you know the distance between 2 tick marks is 2x?? is this an assumption. Would really help to explain. Not sure if I am missing somethinghere
If F = 3^11 = x, then G = 3^12 = 3*3^11 = 3x
Positive difference between G and F = 3^12 - 3^11 = 3x - x = 2x (or 3^12
