Divide the known y's by the known x's:
1/3 = 1/3
2/6 = 1/3
4/12 =1/3
The Y values are 1/3 of the x values.
Multiply the know x value by 1/3 to get y:
y = 9 x 1/3 = 3
y = 3
The best estimate for this correlation would be B) 0.9.
We can see that the number is constantly going up, which would throw out the D answer.
We can also see that for every time the x goes up 1, the y goes up a little less than one. We can see that in the ordered pairs that exist on the graph such as (3, 2), (8, 6) and (2.1, 1.9).
Since the y values are just lower than the x, the correlation would be just under one. Therefore, 0.9 is an accurate estimation.

Divide each by 8
11. Times 8
125 times 8
Use distributive property
5k - 6k -8 = 5x + 4
Combine like terms
-k - 8 = 5x + 4
add 8 to both sides
-k = 5x + 12
k = -5x- 12
