Answer:
B, or in other words, the last solution is correct.
Step-by-step explanation:
Parallel lines haves the same slope, meaning that Street 2 will have the same slope as Street 1. Street one, according to the graph, has a slope of 1. Thus, Street 2 will have a slope of 1.
By this logic, we can get rid of A and C as choices, as they have a slope of -2 or 2. Now we have choices B and D left.
It can't be B, as the slope is -1, not 1.
Therefore, the answer is D.
