What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the point (−3, 1)? y – 1=(x + 3) y – 1=(x + 3) y – 1= (x + 3) y – 1= (x + 3)

The required equation is

Step-by-step explanation:

The equation of given line is

The slope of the given equation is

As we know the slope of parallel line is equal.

Thus, The slope of required line is

Passing point: (-3,1)

Using point slope formula:

Hence, The required equation is

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.

step-by-step explanation:
