Answer:
The second option, or the one attached.
Step-by-step explanation:
This line has a negative slope because the line is going "down the stairs" from the top-left to the bottom-right.

C=(-6,-3)
D=(0,-5)
E=(8,-8)
F=(0,7)
G=(0,-8)
H=(0,4)
I=(-3,-9)
J=(-4,2)
Graph 2:
K=(5,7)
L=(0,-9)
M=(1,3)
N=-7,-5)
O=(7,-1)
P=(0,-1)
Q=(2,-4)
R=(-9,6)
S=(-3,0)
T=(0,9)
Answer:
-8.05
Step-by-step explanation:
In order to solve for C you first have to subtract 17.6 from both sides.
2c=(6/4)-17.6
6/4 is 1.5
1.5-17.6=-16.1
2c=-16.1
c=-8.05
9/5+3/1
24/5 24/5 24/5 24/5 24/5 24/5
Hope this helps! :D
Answer:

B. The coefficient of determination is 0.1980, 19.8% of the variation is explained by the linear correlation, and 80.2% is explained by other factors.
Step-by-step explanation:
Previous concepts
The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.
Solution to the problem
In order to calculate the correlation coefficient we can use this formula:
On this case we got that r =0.445
The determinaton coefficient is just:

And we can put it on % and we got 19.8%. And represent the variation explained by a linear model. The best option on this case would be:
B. The coefficient of determination is 0.1980, 19.8% of the variation is explained by the linear correlation, and 80.2% is explained by other factors.
Since the explained variation is 19.8% and the remain 100-19.8= 80.2% is explained by other factors.
