It means that the coordinates of the point of intersection satisfy the equations of both lines. In the case of simultaneous [linear] equations, these coordinates are the solution to the equations.
They show a comparison between the two graphs. They can show the intersection of the two graphs.
Represent two variables on two axes.
Bar graphs and line graphs are designed to show different values of two or more subjects. They both organize data. They both use an x-axis and a y-axis.
They illustrate the relationship between two (or more) variables.

Bar graphs can compare two sets of data, as well as line graphs and circle graphs. To better improve my answer, double line graphs and double bar graphs compare two sets of data. Circle graphs cannot however, because they compare parts of a whole instead of, as a bar graph would, the amount of something. A circle graph is also incapable of showing data growth over a period of time, as line graphs do. All in all, circle graphs cannot compare to sets of data, and bar graphs and line graphs must be doubled to do so.

They are two dimensional plots in which the coordinates of a simple geometric shape are expressed in the Cartesian plane.
Line and Bar Graph. -Kiddle
The three kinds of graph is bar graph, line graph, and pie graph. bar graph is used to compare two or more things. A line graph is used to show changes over time. A pie graph is used to show proportions.
Bar and line graphs each have at least two labeled axes, and usually a legend.
