Aline passes through the point (4, –3) and has slope m = 1. find the equation in point–slope form. y + 3 = x + 4 y + 4 = x - 3 y - 4 = x - 3 y + 3 = x - 4

The expected answer is ...

  y +3 = x -4

Step-by-step explanation:

The line with slope m through point (h, k) can be written in point-slope form as ...

  y -k = m(x -h)

For (h, k) = (4, -3) and m=1, the filled-in form is ...

  y +3 = x -4

___

It happens that the same line can be described by ...

  y +4 = x -3 . . . . . matches the second choice

because that line also goes through the point (3, -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°
