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 ...

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 ...
