If the inequality is > or< then it is an open circle. If it is greater than or equal to or less than or equal to, it is a closed circle.
In a circle graph it is easier to see shares of the total than in other kinds of graphs.
It is easier because the legs carry the whole weight of the body and if you lift it for a longer time your balance will go.
In an inequality, you have to shade a side of a line to see show if the possible answers are greater than or equal to it
circle graphs create a visual picture of a proportion compared to a whole. Sometimes it is easier to see 25% of this, 15 % of that, and 60 % of something in a circle graph than to hear someone verbally say it to you. Also, you can easily compare two percentages together.
Graphing is not necessarily easier than elimination or substitution. If you are good at drawing graphs, and do not like algebra, then graphing is easier. However, elimination and substitution are much faster, and graphing can often get awkward when working with more complicated formulae.
If the inequality is > or< then it is an open circle. If it is greater than or equal to or less than or equal to, it is a closed circle.
Graphing calculators are true to their name: they can graph out equaitions. Letting the calculator graph out equations is a lot easier than plotting and drawing your own graph, but you do not NEED a graphing calculator. Besides that, their functions are similar to other scientific caculators.
so that you can easily tell what the answer is by extending the line on the graph instead of calculating it
Kepler did not discover ellipses. In 1605 he discovered that the orbits of the planets were ellipses rather than perfect circles.

it is more easier to see which subject has more than the other

Because the diameter is a straight line.

Not greatly. To graph an inequality, you start off graphing the corresponding equality. It is only then that you select one side or the other (with or without the graph itself), as the region of interest.
