I'm taking Physics 11 and we're doing a graphing exercise. The graph is Cricket Chirps per minute(as dependent variable) on the Y-Axis versus Degrees Celsius(Independent Variable) Along the x-axis. I've drawn my line of best fit. The exercise asks that I find the y-intercept of the line of best fit. I've found it to be -65 chirps/minute. The next question asks how would one interpret the y-intercept. This doesn't make any sense to me.. I'm positive I've done the graphing and calculations correctly as the equation works find for finding points on the graph. I've asked my physics teacher some questions and he says they're not correct. I've asked: Is it possible the cricket stops chirping and begins processing chirps. He said no, which leaves me at a dead end. I could just put 'undefined' not sure if that'd be correct though. Also, how would I show this on a graph?
