The two quantitative variables that would likely show a straight line on a scatterplot are:
time spent studying for an exam and the grade on the exam.
This relationship typically suggests that as the time spent studying increases, the grade on the exam tends to increase as well, demonstrating a positive linear correlation. The other pairs of variables do not consistently suggest a straight-line relationship.
