A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation. STEP 1 - Draw ...

There are two types which are full and static. Each with a GraphSystem and line_graph_vis. For full, the data is shown entirely from start to current time/finish. For static (still expreimental!), the ...

It is attractive because it is simple and easy to handle mathematically. It has many important applications. Linear functions are those whose graph is a straight line. A linear function has the ...

Linear equations can be shown on a graph. Find out how to create one in this Bitesize KS3 maths video. A quadratic function can be drawn as a parabola on a graph. Find out how to plot the graph in ...

Linear regression is a method for approximating a linear relationship between two variables. While that may sound complicated, all it really means is that it takes some input variable, like the age of ...

Often in economics a linear function cannot explain the relationship between variables. In such cases a non-linear function must be used. Non-linear means the graph is not a straight line. The graph ...

How well does the line approximate the scatterplot? Then, plot another point that does not lie along the line. How does the regression line change because of the outlier? Clear the graph and plot two ...

Linear Regression in Finance. The goal of a linear regression model is to estimate the magnitude of a relationship between variables and whether or not it is statistically signifi ...
