Answer:
Something is missing from your question. However, the answer is most likely y = 50x
Step-by-step explanation:
For example if you are travelling in a car at 50mph then distance in miles y in terms of the number of hours x would be y = 50x
Answer:
The Inverse Tangent Function (arctan)
Graph of y = tan x.
Y=3x+3
They did 1/3 instead of 3/1
