Answer:
Yes the relationship is linear and given by:
(first option of your list)
Step-by-step explanation:
Yes, it is a linear expression. As we did in previous exercises, we calculate the difference between consecutive y values of the table, and write down the answers we get:
-7-(-2) = -7+2 = -5
-12-(-7) = -12 +7 = -5
-17 - (-12) = -17 + 12 = -5
We notice that all of them give "-5"
Now we evaluate the difference between consecutive x-values in a similar fashion:
-5 -(-9) = -5+9 = 4
-1-(-5) = -1+5 = 4
3-(-1) = 3+1 = 4
We see that they all give 4 as the difference.
That means that the rate of change 
This means that the slope (rate of change) of the line is "-5/4"
We can now use the general point-slope form to write the equation of the line, using the first pair of the table as our selected point, and using "-5/4" for the slope:

which is the first expression listed among your possible answer choices.
Answer: The expression representing the amount of money spent is
by Emily.
Step-by-step explanation:
Since we have given that
Let the cost price of per pair of sandals be 's'
Let the cost price of per pair of boots be 's+30'.
Number of pairs of boots = 2
Number of pairs of sandals = 3
Total cost would be

Hence, the expression representing the amount of money spent is
by Emily.
(33/7) / (1 13/14)
= (33/7)/ (27/14)
= (33/7)* (14/27)
= 22/9
= 2 4/9
The final answer is 2 4/9~

the greatest common factor of 8,44,12 is 4
Answer:
x = 25
y = 65
Step-by-step explanation:
(I did it on Math Nation)
180 = 130 + 2x
50 = 2x
x = 25
180 = 50 + 2y
130 = 2y
y = 65
