Which equations represent the line that’s passes through points (1,-5) and (3,-17)

(1,-5)(3,-17)

slope = (-17 - (-5) / (3 - 1) = - 12/2 = - 6

y = mx + b

slope(m) = -6

use either of ur points...(1,-5)...x = 1 and y = -5

now we sub and find b, the y int

-5 = -6(1) + b

-5 = -6 + b

-5 + 6 = b

1 = b

so ur equation is : y = -6x + 1or 6x + y = 1

Hope this helps!

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°
