As per the rule of the graph of inequalities when we draw a graph of an inequality with sign of greater than ( > ) or the sign of less than ( < ), the area will be shown by upper zone or lower zone of the line. But boundary will be shown by the dotted line.
When inequality has the sign of ( ≥ ) or ( ≤ ) then the line will be drawn as a solid boundary.
x - y ≤ 5 has the sign of ( ≤ ) therefore boundary will be a solid line in this inequality.
