With two points, you can define a line. Write two points that you can use to define the line that represents the situation.

Step-by-step explanation:

Find the Equation of a Line Given That You Know Two Points it Passes Through. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

The points (0, 0) and (1, 20) can be used to create the line that represents the situation.

If t is the x-coordinate and r is the y-coordinate, then any point that satisfies the equation r = 20t for t > 0 can be used to graph the line. So, any two points that satisfy the equation, such as (0, 0), (1, 20), (2, 40), (3, 60), (4, 80), (5, 100), and so on, can be used to create the line that represents the situation. The line is the same in each case.

This is the exact answer on Edmentum.

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
