20 points two
1. a scatter plot with a line is shown below.
[graph shows numbers from 0 to 10 at increments of 1 on the x axis and number s from 0 to 15 at increments of 1 on the y axis. scatter plot shows ordered pairs 0, 1 and 1, 2 and 2, 3 and 3,4 and 4, 4 and 5, 6 and 6, 8 and 7, 8 and 8, 11 and 9, 13 and 10, 15. a line joins ordered pairs 0, 0 and 8, 15.]
which statement is most likely correct about the line?
[i think the answer is a]
it can be the line of best fit because it is closest to most data points.
it can be the line of best fit because it passes through all the scatter points.
it cannot be the line of best fit because it does not show positive association.
it cannot be the line of best fit because it is not closest to most of the points.
2. a scatter plot is shown below:
[a graph shows numbers from 0 to 10 on the x axis at increments of 1 and the numbers 0 to 15 on the y axis at increments of 1. the ordered pairs 0, 14 and 1, 12 and 2, 12 and 3, 13 and 4, 10 and 5, 8 and 6, 5 and 7, 7 and 8, 3 and 9, 3 and 10, 0 are shown on the graph.]
which two ordered pairs can be joined to best draw the line of best fit for this scatter plot?
[i think the answer is a]
(0, 15) and (10, 1)
(0, 15) and (10, 13)
(0, 10) and (5, 0)
(0, 10) and (10, 10)
