Answer: yes
It is a function because when it's numbers to letters your number can I have more than one letter but your letter can't have more than one number if that makes any sense
Q = 3s - 9/6
q = 3(s - 3)/6
q = s - 3/2
6q + 9 = 3s
6q + 9/3 = s
3(2q + 3)/3 = s
2q + 3 = s
s = 2q + 3
It’s a linear function because each x value belongs to only one y value and only one y value belongs to one x value
The slope for the problem is y=−4x−2, so the graph would look like this, intersecting the X line at -0.5 and the Y at -2.
The 4th value is 6 or 6000
