Answer:
a) Function? No
b) Domain: 
c) Range: 
Step-by-step explanation:
a) Function? No
We want to determine whether the graph of the relation is a function or not.
When we draw a straight line at x=-1, it will intersect the graph at several points, therefore the graph fails the vertical line test and hence it is not a function.
b) The domain refers to all x-values for which the function is defined.
From the graph the domain is
because the ends of the graph are closed.
c) The range is the set of all y-values for which the graph is defined.
From the graph the range is 
Answer:
(x, y) = (-10, -7)
Step-by-step explanation:
#1 Multiply the first equation by 7
#2 Then multiply the second equation by 5
1. 14x - 35y = 15
2. 10x - 35y = 55 (-
---------------------------
4x = -40
x = -10
Then go back to equation one and replace "x" with -10
2(-10) - 5y = 15
-20 - 5y = 15
-5y = 15 + 20
-5y = 35
5y = -35
y = -7
The answer is
(x, y) = (-10, -7)
Hope this helps!
Have a nice day!
