Answer:

  B.  3x -7y < -21

Step-by-step explanation:

For this problem, a quick way to the correct answer choice is to determine on which side of the y-intercept the equation tells you the solution lies. That is ...

  • set x=0
  • divide by the coefficient of y

Doing this transforms the answer choices to ...

  A: y < 3

  B: y > 3

  C: y > -3

  D: y < -3

The graph clearly shows the solution space on the y-axis is in the region y > 3, matching choice B.

Suppose the line of best fit is being found for some points that have an r-value of 0.769. If the standard deviation of the x-co
jeyben [28]

r value i.e Correlation between x value and y value = 0.769

A_{x}=Standard deviation of the x-coordinate = 5.508

 A_{y}=Standard deviation of the y-coordinate = ?=k

Slope of line is given by formula

If slope of line is m, then

m = r\times \frac{ A_{x}}{A _{y}}

m= 0.769 \times \frac{k}{5.508}

Substitute the value of k, i.e Standard deviation of the y-coordinate and then you can get the slope of line to three decimal places.
