Answer:
slope: 1/4x, Y intercept: 8
In #12, substitute into the given function the x values {-3, 0, 6} to obtain the range: the function takes on the following values: {0, -1, -3}. Thus, the range for #13 is {0, -1, -3}.
Do the others in precisely the same way.
Answer:

Step-by-step explanation:
step 1
Determine the slope of the dashed line
The formula to calculate the slope between two points is equal to

we have
(-3,1) and (0,3)
substitute


step 2
Find the equation of the dashed line in slope intercept form

we have

---> given problem
substitute

step 3
Find the equation of the inequality
we know that
Is a dashed line and everything to the left of the line is shaded
so

see the attached figure to better understand the problem
The answer to your question is letter F.
