2. Since the inequality is > a dashed line is used, as the points on the line are not included in the solution set. 3. Select a point not on the boundary line: Linear equations are used to model ...

In this video we will learn about the plotting of graphs for a pair of linear equations in two variables. Two straight lines are obtained when we plot a pair of linear equations on the graph paper ...

We will now learn about inequalities containing two variables. In particular we will look at linear inequalities in two variables which are very similar to linear equations in two variables. Linear ...

A linear equation in two variables has infinitely many solutions. • The graph of every linear equation in two variables is a straight line. • The graph of x = a is a straight line parallel to ...

One way to assess this fluctuating data is to add a linear trend line to the Excel 2013 graph. This visual ... a relationship between the two plotted variables, whereas a perfectly horizontal ...
