Slope: constant rate of change
Since one time = 7, it would stay 7
As it’s $4 per game, the slope is the rate of change. “Per game”
Solution: 4
To solve this you can multiply the second equation by to get
3x+6y =18
Then you can subtract it by the first equation to get
7y= 14
And get y= 2
Then you plug in y to one of the equations to find that x=2
