Use this graph to answer these questions:

a. what is the y intercept

b. what is the slope.

c. what does the dashed line tell us?

d. what is the linear inequality equation for this graph.

answer each question individually.

The Visual Language of Dashed Lines. The dashed line is exquisitely rich with information. A line formed from a continuous series of dashes is diminished in strength when compared to a solid line, yet in terms of visual language, it is just as powerful.

            First, graph the "equals" line, then shade in the correct area. There are three steps: Rearrange the equation so "y" is on the left and everything else on the right. or below the line for a "less than" (y< or y≤).

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.
