A line passes through the points (-5, 2) and (10, -1 parentheses. Which is the equation of the one?

 y = -1/5x + 1

Step-by-step explanation:

(-5,2)

(10,-1)

-5 - 10 = -15

2-(-1) =3

3/-15     The slope is -1 /5 but we need to find the y intercept

2= -1/5(-5 ) + b

2 =  1 + b

-1   -1

b  = 1

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°
