*NOTICE* Some of the numbers on your picture are blurry, so the numbers might be slightly wrong *NOTICE*

Step-by-step explanation:

I assume that this is asking you to write the simplest equation.

The three formulas you need are the slope formula, the point-slope formula and the linear equation.

Slope formula is , Point slope is y-y1=m(x-x1), where m is the slope and y1 and x1 come from a point, and linear equation is y=mx+b. Where m is the slope, and b is the y-intercept.

1)Slope=3, and y-intercept=-1, so y=3x-1

2)Slope=-1/5, and y-intercept=4, so y=-1/5x+4

3)Slope=5, and it goes through the point (2,7), so y-7=5(x-2) you distribute the 5 to get y-7=5x-10, and you add the 7 to get y by itself to get y=5x-3

4)Slope=0, and it goes thorough point (-3,3), so y-3=0(x+3). Distribute the zero to get y-3=0. Add thee to get y by itself to get y=3

5)slope=3/4, and it goes through point (0,6), so (0,6) shows that the y-intercept=6. y=3/4x+6

6)Goes through points (6,2) and (5,4), so you use the slope formula to get . y-2=2(x-6), and you distribute the 2 to get y-2=2x-12. Add two to get y by itself, and you get y=2x-10.

7) Goes through (0,4) and (2,7). Slope formula . (0,4) shows the y-intercept=4. y=3/2x+4.

8)Goes through points (-3,2) and (8,2). Slope formula . Point-slope to get y-2=0(x-3). Distribute 0 to get y-2=0. Add 2 to get y by itself to get .

9)Goes through points (-6,1) and (-3,2). Slope formula . Point-slope to get y-1=1/3(x+6). Distribute 1/3 to get y-1=1/3x+2. Add 1 to get y by itself to get .

10)y-intercept=4 and goes through point (2,3). Turn y-intercept into point (0,4). Slope formula. . With y-intercept=4,

answer: 4/6 =5/7.5

step-by-step explanation: it is based on scale and the scale between the two is 1.25. the answer is correct but i dont know if i explained it right

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.
