A is roughly at the point 1.7
B is roughly at the point -1.1
QA = -1.7
QB = -1.1
-1.1 > -1.7 so QB is larger.
What from the graph allows us to assume that it is drawn to scale? Can we say with 100% certainty that A is further from the origin than B?
B is roughly at the point -1.1
QA = -1.7
QB = -1.1
-1.1 > -1.7 so QB is larger.

Note that the line contains three points: (0, 0), (4, 5), and (x, 1.5). The slope between any two of these points is the same. Remember that slope is change in y over change in x. Thus, 5-0/4-0=1.5-0/x-0, or 5/4=1.5/x. Cross-multiply to find 5x = 6.0. Divide by 5 to find x = 1.2. The answer is choice (B).
