As shown in Figure 1, on the number axis, the absolute value of the number represented by point B is 1 times larger than that represented by point a (B is a little more to the left of point 0, and a is a little less to the right of point 0) If the two points of B are 19 units apart, then the number represented by point a is (), and the number represented by point B is ()

A is (19-1) / (2 + 1) = 6
B=-(6*2+1)=-13
