@kbriones0 Multiply the top equation by 2 2x - y = 7 --> by 2 is what?

14?
Directrix
  • Directrix
No. 2x - y = 7 --> by 2 ---> 4x -2y = -14 Add that to the second equation

ok im with you

4x -2y = 14 -4x +2y = -14 ------------- Add those two equations. What do you get.

Look at the attached chart after you add the two equations.

8x-4y-14=0?
Directrix
  • Directrix
No. 0 + 0 = 0 4x -2y = 14 is the same line as -4x +2y = -14. If you multiply -4x +2y = -14 by -1, you will get the first equation. So, there is only one line here. Or, you can say that they coincide in every point.

Your equations intersect in every point. Look on the attached chart and read how many solutions there are. That is the answer to this question.
