Answer:
slope or m = -1
Step-by-step explanation:
The slope formula is:
y2-y1 -3 - 1 -4 -4
-------- = -------------- = --------- = ----- = -1
x2-x1 1 - (-3) 1+3 4
So, the slope is -1 XD YAY!!
we are given inequalities as

Subtract both sides by 1


so, we get interval as
![(-\infty,-4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-4%5D)
we have

we can divide both sides by -4


so, we get interval as

now, we can combine them
∪
now, we can draw number line and locate this interval
we get
The answer is 27/4 or 6 3/4
B. (5,2)
(-1 + 11)/2 , (9 - 5)/2
10/2 , 4/2
5,2
