Line AB contains points A(4, 5) and B(9, 7). What is the slope of AB?

the slope is 2/5

Step-by-step explanation:

because the 4 in (4,5) is the x value meaning it moves horizontally and horizontal is the run of the slope (the denominator of the slope) so you run 5 to the right making it positive and you rise 2 which is the y value so the rise over run (slope) is 2/5

step-by-step explanation:

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°
