Question

table 6 room temperature
time* (min) 0 5 10 15 20
classroom temperature (°c) a 16 17 19 20 20
b 16 17 19 21 23
c 16 16.5 17 17.5 18
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?
\time\ would be on the y - axis and \temperature\ would be on the x - axis.
\temperature\ would be on the y - axis and \time\ would be on the x - axis.
\time\ would be on the y - axis and \classrooms a - c\ would be on the x - axis.

Explanation:

Step1: Recall graph - axis convention

In a line - graph, the independent variable is plotted on the x - axis and the dependent variable is plotted on the y - axis. Here, time is the independent variable as the temperature of the classrooms changes over time. The temperature of the classrooms is the dependent variable.

Answer:

"Time" would be on the x - axis.
