It is B.
You see that the line segment crosses the y-axis at 1? That is known as the y intercept.
Remember y = mx + b?
Well in this graph, b = 1
Therefore it is B
X + y = 40.....multiply by -4
4x + 6y = 180
-------------------
-4x - 4y = -160 (result of multiplying by -4)
4x + 6y = 180
------------------add
2y = 20
y = 20/2
y = 10 <===
x = 30
