Revise how to work out the gradient of a straight line in maths and what formula to use to calculate the value change in this Bitesize guide.

This section focuses on the key features and methods for working with linear graphs. It demonstrates how to sketch graphs from rules, derive rules from graphs, and calculate key features such as the ...

Excel's intercept function takes the data points that define a line on a graph and calculates the y value for the point on the graph where x is equal to zero.

How to Estimate the Y Intercept in Excel. When you graph a series of (x,y) coordinates in Microsoft Excel 2010, you can use the program's built-in functions to display the equation for the line ...

Just like we can calculate the use derivative of a function f ( x ) to calculate the slope at a given value of x on the graph and thus our next step. Here, we calculated the partial derivative with ...

At a high level, the gradient descent approach is used to find the set of parameters, in this case, the intercept and weights of the linear regression model, that minimizes some cost function. The ...
