In math and statistics, you may occasionally need to calculate the slope of a line generated by coordinates in the (x,y) format. The slope is a value that indicates the rate at which the y value of a ...

Other students will draw the tangent line to the graph at t = 30 -- without ever having been told what a tangent line is or having seen one -- and measure its slope. The first approach, of course, is ...
