Is this a relation: {(-2,1), (0,0), (0,1), (1,-2), (1,0), (1,3), (2,0)}? Explain why or why not.

It is a relation because any relation is simply a set of (x,y) values known as points or ordered pairs. There are no other qualifications needed to be a relation. We simply pair up any x and y value we want.
I think you meant to ask if it's a function or not. If so, then the answer is "no, it is not a function". Why not? Because the x value x = 0 produces more than one y output y = 1 and y = -2. Graph these points and you'll see them fail the vertical line test (ie its possible to draw a vertical line through more than one point on the graph). The same issue happens with (1,-2), (1,0) and (1,3) as well.
In summary:
Yes it is a relation
No it is not a function
The reasoning for each is stated above
Answer:
negative
slope= -1/4
Step-by-step explanation:
Answer:
-50
Step-by-step explanation:
b-5 
b-5 = -45 ( collect like terms)
b = -45 + -5
b = -45 -5 b = -50
The answer would be: t= -5/4
Answer:
<h2>
a) 0.38</h2><h2>
b) 0.62</h2><h2>
c) 0.78</h2><h2>
d) 0.03</h2><h2>
e) 0.02</h2><h2>
f) 0.62</h2><h2>
g) 0.38</h2>
Step-by-step explanation:
a)
Probability of a owner to be moved = 
= 0.379 ≅ 0.38
b)
Probability of a renter to be moved = 
= 0.62
c)
Probability of a person who moved in the same state = 
= 0.779 ≅ 0.78
d)
Probability of a person who moved to a different country = 
= 0.033 ≅0.03
e)
Probability of a owner who moved to a different country = 
= 0.02
f)
Probability of a renter moving in the same state = 
= 0.615 ≅ 0.62
g)
Probability of an owner moved to different state = 
≅0.38
