Two lines are defined by the equations below. -2x + 5y = -13 12y = 4x - 34 Which set of statements shows that the point (-3.5, -4) is the point where the two lines intersect?

• A. -2(-3.5) + 5(-4) = -13 12(-4) = 4(-3.5) - 34

• B. -2(-3.5) + 5(-3.5) = -13 12(-4) = 4(-4) - 34

• C. -2(-4) + 5(-3.5) = -13 12(-4) = 4(-3.5) - 34

• D. -2(-3.5) + 5(-4) = -13 12(-3.5) = 4(-4) - 34
