Two lines, a and b, are represented by the equations given below:

line a: y = x − 6
line b: y = 3x + 4

which of the following shows the solution to the system of equations and explains why?

(−5, −11), because the point satisfies both equations
(−5, −11), because the point does not lie on any axis
(−3, −5), because the point satisfies one of the equations
(−3, −5), because the point lies between the two axes
