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.

In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed. The gradient of a line is calculated by dividing the difference in the ...

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 ...

As a tangent is a straight line it is described by an equation in the form \(y - b = m(x - a)\). You need both a point and the gradient to find its equation. You are usually given the point - it's ...
