Answer:

Step-by-step explanation:
We find slope by; change in y ÷ change in x,
Change in y = -4 - 3 = -7
Change in x = 7 - - 2 = 9
Slope of line MN = -7 ÷ 9 = 
The answer is C because if you substitute in X-6 for the y in the first equation (since X-6 is also equal to y), you get 2x=16 which means x=8. There is only one option where 8 is equal to X, but just to check you can substitute it back into either of the original equations to make sure that y=2.
8x would represent multiplying 8(people) times x(ticket cost) But you don't know how much the tickets cost per person so that's why it's x.
8x + 20 = 76
76-20=56
56÷8=7
x equals 7
