Answer:
Domain 
Range
Step-by-step explanation:
Domain : Domain of a function 
is the set of all possible values of 
for which exists.
Range : range of a function is the set of all possible values of .
Here 
can be any value from 
to 
.
hence possible value of can be any value between and
let 
so 
.
hence can have any value between 
.
Range

Answer:
Choice B: Only (-1,-5)
Step-by-step explanation:
With this one, first the equation needs to be reduced into point-slope format.
y+5=2(x+1)
Distributive Prop.
y+5=2x+2
Carry over the 5 to the opposite side.
y=2x-3
Now, with the point slope form, it makes it easier to plug in the question choices to find which if any are correct.
Choice A: X is 5; Y is 10
y=2x-3
y=2(5)-3
y=10-3
y=7
This does not give a y value of 10, so it is false.
Choice B: X is -1; Y is -5
y=2(x)-3
y=2(-1)-3
y= -2-3
y= -5
This does give a y value of -5, so it is true. Choices C and D are therefore false as well, since only Choice B works.
