Write the equation for a line perpendicular to y=3x-5 and passing through the point (-3, -1)

Step-by-step explanation:

Given equation of line is y=3x-5

Given equation is in the form of y = mx + b

where m is the slope

Slope of the line = 3

Slope of perpendicular line = negative reciprocal of slope of given line

Slope of perpendicular line =

We got slope m= -1/3  and point (-3,-1) (x1=-3  and y1=-1)

Lets find equation of perpendicular line  using point slope formula

Plug in the values

Distribute -1/3 inside the parenthesis

Now subtract 1 on both sides

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°
