A graphic solution is when you answer a question by graphing.
A graphic solution is when you answer a question by graphing.
xy4*sqrt(xy)
The solution is the coordinates of the point where the graphs of the equations intersect.

By graphing the lines on the coordinated plane they will intersect at (2, -4) which is the solution of the equations
Graphing
When graphing inequalities you use a circle to indicate a value on a graph. If the value is included in the solution to the inequality you would fill in the circle. If the value that the circle represents is not included in the solution you would leave the circle unshaded.
In graphing, a solid line indicates that the points on the line are included in the solution set. This is typically used in the context of inequalities where the relationship is inclusive, such as ( \leq ) or ( \geq ). In contrast, a dashed line would indicate that the boundary points are not included in the solution.
When the value represented by the circle is part of the solution set.
A model in mathematics is a physical representation of the solution. This can be done by graphing, illustration, or creating an equation or function.
