Scatter Plot Christa Moore

Which equation best represents the data?

•  y = x + 2

•  y = -x + 2

•  y = x - 2

•  y = -x - 2 

Which equation best represents the data?

•  y= -3/5x + 2

•  y = 5/3x -2 

•  y = -3/5x - 2

•  y= 5/3x + 2

Which equation best represents the data?

• y= -2/3x - 4

• y= 2/3x - 4

• y= -3/2x - 4

• y= 3/2x + 4

What type of association does this graph have?

• positive 

• negative

• none

• all of the above

Which scatter plot shows a linear relationship between x and y?

• Graph A

• Graph B

• Graph C

• Graph D

What is the correlation?

• Negative correlation

• No correlation

• Positive correlation

• All of the above

If a scatterplot has no correlation then...

• ...it has no ordered pairs

• ...it has ordered pairs that have a negative pattern

• ...its ordered pairs have no predictable pattern

• ...if it makes a lion on a graph (roar!)
