ANSWER
Graph B
Step-by-step explanation
We have to select the graph that shows the system.
In this case, we have two lines: the first one is a line with a positive slope passing through the point (0, -3) since -3 is the y-intercept. Only graphs B and D show a line with these characteristics.
The second equation is also a line. If we solve that equation for y, we can identify both the slope and the y-intercept,

So the graph of the second equation is a line with a negative slope passing through the point (0, 1) since 1 is the y-intercept. The only graph that has two lines with the characteristics mentioned is graph B.
Hence, the graph showing the system is graph B.
