Step-by-step explanation:
The solution to a system of equations is the intersection point of two or more lines on a graph.
In this case, we see that at (1, 3)
Remember that this question is asking for the y intercept, not the full coordinates or the x intercept.
We know that the full coordinates are (1, 3), or (x, y), and since we need y, we know the y cooridnates are 3, not 1, since this is x.
So the first answer, A, is correct.
Hope this helps!
