Explain why the two equations below have the same solutions.
x + 3y = −1
−2x − 6y = 2
a. the two equations have the same slope, so they have the same solutions.
b. the second equation is a multiple of the first equation, so they have the same solutions.
c. the graphs of the equations are parallel and do not intersect, so any solution of one is a solution of the other.
d. the lines are perpendicular, so they have the same solutions.
