Plot linear equations in two variables on the coordinate plane. Use intercepts to plot lines. Use a graphing utility to graph a linear equation on a coordinate plane.We can plot a set of points to represent an
The following diagram shows how to graph the linear inequality 2x - 3y ≥ 6. Scroll down the page for more examples of graphing linear inequalities. Example: Show the region represented by the inequalityx + y< 1 Solution: Rewrite the equationx + y= 1in the formy=mx + c. x + y=1 ...

In this case, the relationship is that the y-value is twice the x-value.There are multiple ways to represent a linear relationship—a table, a linear graph, and there is also a linear equation. A linear equation is an equation with two variables whose ordered pairs graph as a straight ...

An inequality may be solved in the same manner as an equation: by applying the same operation (addition, subtraction, multiplication, or division by a number) to both sides until it is in the desired form (x = k for one-variable, y = mx + b or ax + by = c for two-variable). ...
For graphinginequalities with two variables, you will have to plot the "equals" line and then, shade the appropriate area. There are three steps: Write the equation such as "y" is on the left and everything else on the right. Plot the "y=" line (draw a solid line for y≤ or y≥...
