When graphing inequalities where can solutions be found?

I think that you are asking about the linear inequalities with two variables, so my answer is related to them. First, you have to draw the boundary line (be careful, if your inequality does not contain the equal sign, the boundary line will be a dashed line, because the points on the line are not solutions to the inequality), which divide the coordinate system in two half-planes. Second, you have to test a point on either sides of the line (the best point is the origin, (0, 0), if it is not on the boundary line). If that point satisfies the inequality, then there are all its solutions, otherwise they are to the opposite side.

How would you know that the boundary line is enclosed in a graph?

The boundary line is solid. If not it will be a dashed line.


Which type of line follows the outline of an object?

It depends upon the dimensions that you are working with.In one dimension all level are mundane and all lines are simply referred to as 'the line'.In two dimensions it depends upon which direction you proceed from a reference point. If the point is contained within the boundary of the line then all parts of the line are 'the out-line'. If the point is exterior to the line boundary then all parts of the line are 'the in-line'.In three dimensions there are nine variations to proceed from a point of reference and are (now-a-days) referred to in ordered of their level hierarchy.out out outout out inout in outin out outout in inin out inin in outin in inmundane -- unity with the point of reference.
