Answer:
c ≥-8
Step-by-step explanation:
I got this answer because all you have to do is subtract 9 on both sides and then that is the answer.
It just so happens that it's always the same y for each x, but it is only that one y. So this is a function; it's just an extremely boring function! ... So this is a relation, but it is not a function.
P=2L+2W
P=(2*4)+(2*8)
P=8+16
P=24
Graph using slope and the y intercept
So y=x+5
You would plot the y intercept (0,5) and then go up 1 and to the right 1
The next graph plot y intercept (0,-1) and then go down 2 and to the right 1
And should look like the image
And your solution should be (-2,3) which is option c
