Question 506437: I'm not sure how to determine whether or not a function is linear. I know and understand what a linear function is, but I'm not sure how to immediately determine it. I know it has something to do with f(x)= mx+b. My teacher taught me something about A, B, and C. I'm not sure what he exactly means by this. The problems I'm having trouble are:
1. x/2=10+2y/3
2. 3a+b-2=b
3. 3m/4= 2n/3-5
Is there anyway where I can immediately identify it as linear or non-linear without graphing it or testing the function out?
