Answer: No
Step-by-step explanation:
2.7 + 3.5 is not greater than 9.8.
(-1, 5) because if you plug in -1 to both equations, you should get 5 from both equations. They also cross at that point, making that the solution.
It should be y1 - y2/x1 - x2 this is supposed to be a fraction
I end up getting -31 - 24/5 + 6 or -31 -24/5 - (-6)
