Write a rule for linear function in the graph (4,3) (3 ,-1)

D) y = 4x - 13

Step-by-step explanation:

Slope: the change in y over the change in x

In a equation in slope-intercept form is in y = mx + d, where m is the slope.

The slope can be found by its definition. As y goes up by 4, x goes up by 1, so the slope is 4/1 = 4.

The only option with 4 as the slope is D.

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°
