Algebra Correlation

If the correlation coefficient, r, of a data set is r = -0.95. What type of correlation does the data have?

• Strong Positive

• Strong negative

• Weak Postive

• Weak Negative

• No correlation

Line on a scatterplot that fits most points.

• Line of Best Fit

• Positive Correlation

• Parallel Lines

• Horizontal

  Line

Point where the graph crosses the X-Axis

• X - Intercept

• Y - Intercept

• Zero

• Decay

6x - 2 - 7x + 4 - x

• -2x + 2

• -2x - 2

• 2x - 6

• x + 2

-3(x - 3) + 6(x + 1)

• 3x + 6

• 3x + 4

• -3x + 16

• 3x + 15

4a + 8 = -20

• -6

• -7

• 3

• -3

8(x - 1) = 4(x + 4) - 2x

• 2

• 6

• -2

• 4

Give an equation of a line that is parallel to the line y = -3x

• y = 2/3x - 2

• y = 3x + 2

• y = -3x - 1

• y = -2/3x + 3

What are the intercepts for 3x - 2y = 6

• (0, 3) and (2, 0)

• (0, -2) and (-3, 0)

• (0, -3) and (2, 0)

• (0, 2) and (3, 0)
