Find the slope of the line through the pair of points.

Question

Find the slope of the line through the pair of points.

(-9, -9) and (5, 6)

Answer 1

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.

Answer 2

Find the slope of the line through the pair of points.

(-2, -5) and (5, -5)

Answer 3

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.

Answer 4

Find the slope of the line through the pair of points.

(9, 9) and (5, 5)

Answer 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.

Answer 6

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?

Answer 7

Based on the given situation, it is likely that there is a negative correlation between the number of attendees at an outdoor event and the percent likelihood of precipitation. This means that as the percent likelihood of precipitation increases, the number of attendees is likely to decrease. However, it is important to note that this correlation does not imply a causation. In other words, the change in the number of attendees does not necessarily cause a change in the percent likelihood of precipitation. Other factors, such as availability of shelter or potential discomfort due to rain, could also influence the number of attendees.
