The aim is to give an elementary, thorough systematic introduction to the subject. This will also help us understand the adjective \linear" a bit better. First, the addition of two linear equations results in a new equation that is linear. 37 … Basic Linear Alebra 2. Using the same number and result they will be asked to equate them in as many ways as possible using a maximum of two operations. (cont) linear or non linear: the graph is a straight line; On the pattern, you always add or subtract the same number of squares; On the table, you always add or subtract the same number from step to step; On the graph, you can observe a straight line. Applications of Linear Equations: Introduction to Problem Solving. For example, with xand y instead of x 1 and x 2, the linear equation 2x+ 3y= 6 describes the line passing through the points (3;0) and (0;2).
