You add the second equation to the first which eliminates x and leaves you with 2y=18 so you divide 18 by 2 which is 9 so y=9 now you fill in one question for y so do x+4(9)=9 you get x+36=9 now subtract 36 from 9 and you get -27 so x=-27 and y=9

The scenario represents a linear function. The rate is at a constant increase therefore it is linear.
Linear because it’s a constant rate
Since it’s doubled, and doesn’t go at a constant rate, it is a exponential function
Exponential since it increases by a multiplicative rate. It’s not constant
