If you're writing the DSAT, it would be better if you used the graphing calculator. It makes it easier. Some calculator apps have graphing calculators, especially the ones on laptops.

Just watch the sign . If y is <= mx+b then we should shade in lower region from the boundary of line . same as If y is >= mx+b then we should shade in upper region from the line boundary . After shading both region check the overlapping region which contain both shaded region of two line . Basically that region is the solution for both inequalities. If you still don't understand then I recommend you to check the Things to remember section of previous page where you can get the concepts.

I get confused how to identify the upper and lower part

Just do more practice and make sure to watch the videos on the lesson prep, it really helps, goodluck btw!!

How is Sal determining which region would be included?

Basically, if you see the > sign on an inequality it tells you that you shade the region above the line whereas if you see the < sign on the inequality it tells you that you should shade the region below the line.

How is Sal determining which region would be included?

if y>mx+c, the upper part of the line is to be shaded and if y<mx+c, shade the lower part of the line.

  Just watch the sign . If y is <= mx+b then we should shade in lower region from the boundary of line .
  same as If y is >= mx+b then we should shade in upper region from the line boundary . After shading both region check the overlapping region which contain both shaded region of two line . Basically that region is the solution for both inequalities.
  If you still don't understand then I recommend you to check the Things to remember section of previous page where you can get the concepts.

  y>-3x+3.the shaded line will be the greater side of the inequality.It is better to do with example (1,0).... and use a graph paper/do normally with points.
  
  Take a point on the line and move the point along y axis you will know outside the shaded region all values of y are smaller than inside shaded region
