Find the slope of the line through the pair of points.
(-9, -9) and (5, 6)
The slope of the line through the points (-9, -9) and (5, 6) can be found using the formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the values:
m = (6 - (-9)) / (5 - (-9))
= (6 + 9) / (5 + 9)
= 15 / 14
Therefore, the slope of the line is 15/14.
Find the slope of the line through the pair of points.
(-2, -5) and (5, -5)
The slope of the line through the points (-2, -5) and (5, -5) can be found using the formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the values:
m = (-5 - (-5)) / (5 - (-2))
= (-5 + 5) / (5 + 2)
= 0 / 7
Therefore, the slope of the line is 0.
Find the slope of the line through the pair of points.
(9, 9) and (5, 5)
The slope of the line through the points (9, 9) and (5, 5) can be found using the formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the values:
m = (5 - 9) / (5 - 9)
= (-4) / (-4)
= 1
Therefore, the slope of the line is 1.
For a strong correlation, people often assume that change in one quantity causes change in the second quantity. This is not always true. For the following situation, predict the type of correlation you might find. Do you think that change in the first quantity causes change in the second quantity?
the number of attendees at an outdoor event and the percent likelihood of precipitation
What correlation, if any, is there between the quantities?
