which two quantitative variables would show that a straight line will be produced on a scatterplot
Two quantitative variables that would show a straight line relationship on a scatterplot are:
1) Age and years of education: It is expected that as age increases, the number of years of education also increases in most cases. This positive linear relationship would result in a straight line on a scatterplot.
2) Distance traveled and time taken: Assuming a constant speed, the distance traveled would be directly proportional to the time taken. Therefore, the relationship between these variables would produce a straight line on a scatterplot.
