Liam and Sarah have each drawn a line on the scatter plot shown below: The graph shows numbers from 0 to 10 on x and y axes at increments of 1. Dots are made at the ordered pairs 1, 7 and 2, 6 and 3, 5.5 and 4, 5.8 and 4.5, 4.8 and 5, 4 and 6, 3.5 and 7, 3 and 8, 2.9 and 9, 2.2 and 10, 1.5. A straight line labeled Line A joins the ordered pairs 0, 7.2 and 10.4, 0. A straight line labeled Line B joins the ordered pairs 0, 7.2 and 9.8, 0.

Which line best represents the line of best fit?

Line A, because it shows a positive association
Line A, because it is closest to most data points
Line B, because it is closest to most data points
Line B, because it shows a negative association

the answer is 0.071

good luck! : d

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
