Answer:
A
Step-by-step explanation:
Lets first solve the relation for "y". Shown below:
This is clearly an equation of a line in the form 
It will be a negatively sloped line, when graphed.
We can use vertical line test to determine function or relation. If a vertical line passes through only 1 point in the graph, we say that it is a function.
Think of a negatively sloped line. No matter where you draw a vertical line, it will only cut the line at 1 point.
So, this is definitely an equation of a function
Correct answer is A
(-3, 6) includes all numbers between -3 and 6 but it does not include -3 and 6.
when you put square parentheses you include the number on the edge
so if an anwser includes all numbers between -3 and 6 and the number 6 it's correct to write (-3,6]
Answer:
Its D
Step-by-step explanation:
If r is less than q, then it is on the left side because that is the lowest position avaliabe on the number line. If s is q+1, that means s is one more than q so s is bigger than q. If q is more than r and less than s, it is in the middle of those two. So, r is on the left most side, q is in the middle, and s is on the right side because it is the most.
Parallel line means the same slope
（8-1）/(-17-a)=(1-5)/(a+2)
so a is 18
