Below is a graph of test scores in a math class. determine if the points earned for each correct answer is proportional or not proportional. explain your answer.

do you know how to find slope? just find the slope for each one, and if they have the same slop they are  proportional. Tbh without doing the math it looks like they are proportional because all the points like on the same line.

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°

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
