Some students do this by arguing that the graph from t=0 to t=60 is essentially linear already; that tiny bit of curvature we see is so small it can be neglected, so just find the slope of the “line” ...
An equation of the form \(y = mx + c\) where \(m\) and \(c\) are numbers, gives a straight line when values of \(x\) and corresponding values of \(y\) are plotted on a grid. A straight line is a ...
