Which systems of equations has a solution of approximately -2,7 , -1,2 a. 4x - 5y = -5 and 3x + 10y = - 20 b. 4x - 5y = 5 and 3x + 10y = 20 c. 4x - 5y = 5 and 3x + 10y = - 20 d. 4x - 5y = -5 and 3x + 10y = 20

The point of intersection you are concerned with is the left-most of those of the graphed lines. Thus you want the two equatons that both have x-intercepts that are negative. Since the x-coefficient is positive in every case, this will mean the right-side constants of these equations both need to be negative. The appropriate choice is ...
  A. 4x - 5y = -5 and 3x + 10y = -20
