Solving the Inequalities using graph, first you have to take the inequality equation into equal. Then convert the equation into straight line equation i-e(y=mx+c). Giving own values for 'x' like (-1, 0, 1) we would get the value for 'y'. By plotting these points in the graph, you will get an straight line. If the given equation is greater than symbol, shade towards the positive part. If the given equation is smaller than symbol, shade towards the negative part. This is an one method to solving the inequalities using graph. You can shade and find using substituting method, by giving 'x' values in inequalities equation and shade.
