How to graph a line with a slope of 2 and (0,-8) y-intercept

If i am understanding your question correctly the slope equation would be y=2x+(-8)

Step-by-step explanation:

So 2 is gonna be your slope -8 is your y intercept, you are going to put a point at (0,-8) and the slope is always rise over run so you are going to rise up 2 points on your y axis and move to the right 1 unit on your x axis. You should have two points now, to finish your line keep going up 2 units and to the right 1 unit.

Hope this helps!

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

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.
