b. the function's range
c. the x-intercepts, if any
d. the y-intercept, if any
e. the function values, f(-4) and f(-2).
Assume that the graph of the function
continues its trend beyond the displayed coordinate grid.
a. What is the function's domain?
(Type your answer in interval notation.)

Where’s the stuff st? ? lol sorry

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
