Write an equation of a line that passes through the point (2, 3) and is parallel to the line y = 2x+5.
a- y= -2/3x
b- y= -2/3x-7
c- y= 3/2x
d- y= 3/2x+7

i think that you should ask google for the answer to that problem because if we don't know it google does

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°

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
