b. number of Democrats and Republicans in the Senate during the past decade
c. monthly sales of 2 different types of cars during a one-year period

*MUST EXPLAIN*

Answer 1

Hey there!

The correct answer is C.

"Monthly sales of 2 different types of cars during a one-year period" is the type of information that is suited for display on a double line graph.

A double line graph is a graph with two lines, so C would be correct because this choice mentions 2 different types of cars during a one year period.

Hope this helps, have a wonderful day! :)

Answer 2

d. all of these answers

For the first one (a), two lines are needed. One is for Melody's height, the other for Melody's weight.
For the second one (b), two lines are also needed. One is for the Democrats, the other for the Republicans in the senate
For the third one (c), two lines are needed. One line for each type of car.


hope this helps
