To solve it by coordinate graphs you would take a point from the line and plug in the X and Y value into the equations and or inequalities.
It is a point that may or may not be a solution to the system - depending on whether or not the inequalities are strict.
The graphical method is a method used to solve algebraical problems by using graphs.
None of the graphs that I can see!

Sure. Visualize the graphs of two half-planes, each representing a linear inequality. Those can overlap, or they might not overlap. For example:x > 2, andx < 0But a similar example can be made with two variables, as well.x + y > 3x + y < 2If you graph it, you will get two half-planes that don't touch.If you look at the equations, for any combination of values for x and y, the result can't be both more than 3 and less than 2, so there is not a single solution.
Four ways to graphically present data are through bar graphs, pie charts, line graphs, and scatter plots. Each type of graph is best suited for displaying different types of data and relationships between variables. Choose the graph that fits best with the data you are trying to communicate.
The following is the answer.
The graphical method is a method used to solve algebraical problems by using graphs.
The solution to a system of inequalities is where the solutions to each of the individual inequalities intersect. When given a set of graphs look for the one which most closely represents the intersection, this one will contain the most of the solution to the the system but the least extra.
Communications used in a business include; verbally, this is directly by word of mouth or by phone calls. Graphically, through graphs - line graphs, bar graphs is usually used to compare things as it is much easier to see a comparison, for example it is used to compare level of sales each year.
A bar chart (and other graphs) enable you to quickly visualise graphically data that would be confusing if the data was simply a list of numbers.
The graphs of inequalities often intersect. Let's look at a simple one. x<5 and x>4. The intersection is all x such that x>4 and x<5 or those numbers between 4 and 5 not including 4 and 5 itself. If I want to include 4 and 5, just change it to < or = instead of strict inequality. Sometimes there is not an intersection. For example, x < 4 and x > 4, or x < -4 and x > 5, ... .
