Aline in the cartesian plane passes through the points (–2, 4) and (2, –1). what are the rise and the run of the line?
a. the rise is –5, the run is 4.
b. the rise is –4, the run is –5.
c. the run is –5, the rise is 4.
d. the run is 4, the rise is 5.

a. The rise is –5, the run is 4.

Step-by-step explanation:

Given :- A line in the Cartesian plane passes through the points (–2, 4) and (2, –1)

Let and

We know that rise of a line = vertical change of points=change in the coordinates of y

=

Run of line=horizontal change of points=change in the coordinates of x

=

Therefore, The rise is –5, the run is 4.

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°
