We are given a line with the following data:
r-value = 0.657 (r)
standard deviation of x-coordinates = 2.445 (Sx)
standard deviation of y-coordinates = 9.902 (Sy)
We are asked to find the slope of the line up to 3 decimal places.
To find the slope of the line, based on the data that we have, we can use this formula:
slope, b = r * (Sy / Sx)
substitute the values to the formula:
b = 0.657 * ( 9.902 / 2.445 )
Solve for the b.
Therefore, the slope of the line is
b = 2.66078, round off to three decimal places:
b = 2.661 is the slope of the line.
The answer is 4 and 9, this is because 2*2=4 and 3*3=9, so their square roots are 2 and 3
The green arrow thing is a ray. So, question b. is a ray. So the dot would be B and the arrow would be C.

Answer:
638
Step-by-step explanation:
1. Isolate the variable 881 = k - (-243)
-243 -243
2. combine like terms 881 - 243 = k
3. answer 638
