Which of the following are point-slope equations of the line going through (-4,-7) and (3, 2)? Check all that apply.
PLEASSSEEE HELP I’VE BEEN STUCK ON THIS FOR A COUPLE OF DAYS .. 15 points

The equations of the line are

y + 7 = (x + 4) ⇒ B

y - 2 = (x - 3) ⇒ E

Step-by-step explanation:

The point-slope form of the linear equation is

, where

∵ The line passes through points (-4, -7) and (3, 2)

∴ x1 = -4 and y1 = -7

∴ x2 = 3 and y2 = 2

→ Use the rule of the slope above to find it

∵

∴ The slope of the line is

→ Substitute the values of m and (x1, y1) in the form of the equation above

∵ y - -7 = (x - -4)

∴ y + 7 = (x + 4)

∴ The equation of the line is y + 7 = (x + 4)

→ Substitute the values of m and (x2, y2) in the form of the equation above

∵ y - 2 = (x - 3)

∴ The equation of the line is y - 2 = (x - 3)

→  Look at the answers to find the same equations

∴ Answers B and E have the same equations

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.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
