A biologist measured the length and mass of 20 reptiles. The equation y=0.3-2 is the line of best fit for the data, where x is the length, in centimeters, and y is the mass in grams Based on the equation, what is the approximate length of a reptile that’s has a mass of 20.5 grams?

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

Chope this have a nice day btw the other person deserves brainlest
