...
What is the slope of the line?
A. The slope of the line is
(Type an integer or a simplified fraction.)
B. The slope of the line is undefined.

-2

Step-by-step explanation:

Slope = (4-8) / (9-7) = -4/2 = -2

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°

maya’s expression will generate the wrong sum because she violated the commutative property.
