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 ...

Solving linear inequalities Inequalities are generally solved using the same steps as for equations, except when multiplying or dividing both sides of an inequality by a negative number, in which case ...

Overview MATH 270 is suggested for students in the Science programs. The course covers systems of linear equations, matrices, inverse of a matrix, determinant, vectors in two-, three- and n-dimensions ...

Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + b. Linear functions are widely used in economics, physics, finance, and data ...

A linear regression is a statistical model that attempts to show the relationship between two variables with a linear equation. A regression analysis involves graphing a line over a set of data ...

Solving equations with light. (Courtesy: iStockphoto/Henrik Jonsson) 3 x + y = 2 x + 3 y = 0 It’s the sort of easy maths problem that you can work out in a few minutes using pencil and paper, but ...

Simple and multiple regression models are two common ways to analyze the relationship between variables in statistics. Both models use a linear equation to describe how one or more predictor ...
