Ill give u brainliest pls

the tables below show four sets of data:

set a
x 1 2 3 4 5 6 7 8 9
y 10 9 8 7 6 5 4 3 2

set b
x 1 2 3 4 5 6 7 8 9
y 3 4 5 6 7 8 9 10 11

set c
x 1 2 3 4 5 6 7 8 9
y 8 6 5 4 3.5 3 2.5 2 2

set d
x 1 2 3 4 5 6 7 8 9
y 1 2.5 2.5 3 4 5 6 8 9

for which set of data will the scatter plot represent a positive linear association between x and y?

select one:
a. set a
b. set b
c. set c
d. set d

Set B.

Step-by-step explanation:

Not A or C: as x goes up, y goes down. :(

D is correct, but not the best because B's is more clear, as when visualizing the graphs, B's makes a perfect line, as where in D, it is bumpier.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
