When learning algebra, one of the most crucial skills to acquire is understanding how to graph linear equations. It helps you visualize relationships between variables and solve mathematical problems.

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 ...

We begin by defining a new notion of what it means to approximate a graph by another graph, and explain why these sparse approximations enable the fast solution of linear equations. To build these ...
