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 ...

Python allows free creation of plots, unlike expensive, stagnant graphing calculators. Import NumPy and Matplotlib for basic ...

The gradient is the measure of slope of a line. In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed. The gradient of a ...

How about another example ... graph of velocity vs. time? What time would we associate the average velocity with? Probably the only fair thing would be to take two time points and find the slope ...

The graphs above ... a gradient of 3 will be parallel to \(y = 3x + 7\). Two examples are \(y = 3x - 2\) and \(y = 3x + 11.6\). Find the equation of a straight line that is perpendicular ...
