There are some good habits to develop that will help you solve all kinds of linear equations. We’ll summarize the steps we took so you can easily refer to them.Solve an equation with variables and constants on both sides Choose one side to be the variable side and then the...
A linear inequality is an inequality in two variables whose graph is a region of the coordinate plane that is bounded by a line. Graph the following inequality: x > 2 Boundary is: x = 2 We shaded at the right of the line because x is more than 2. The line is dashed because it is...
