Question

table 6 room temperature
time* (min) classroom temperature (°c)
0 a: 16 b: 16 c: 16
5 a: 17 b: 17 c: 16.5
10 a: 19 b: 19 c: 17
15 a: 20 b: 21 c: 17.5
20 a: 20 b: 23 c: 18
25 a: 20 b: 25 c: 18.5
*minutes after turning on heat
multiple choice question
if you were to create a line graph of this table, what variable would be represented on the y - axis and what variable would be on the x - axis?
o \time\ would be on the y - axis and \classrooms a - c\ would be on the x - axis.
o \temperature\ would be on the y - axis and \time\ would be on the x - axis.
o \time\ would be on the y - axis and \temperature\ would be on the x - axis.

Explanation:

In a line - graph, the independent variable is plotted on the x - axis and the dependent variable on the y - axis. Here, time is the independent variable as it progresses regardless of the temperature, and temperature depends on the time elapsed after turning on the heat.

Answer:

"Temperature" would be on the y - axis and "Time" would be on the x - axis.
