Question 1162030
Three points (x,y); x for ticket price, y for average seats sold;  
{{{y<=200}}}{{{just}}}{{{a}}}{{{restriction}}}.
and the points  (24,180), (36,160), (45,145).
You can make a table if you want.



For these to be on a line,  slope {{{m=(160-180)/(36-24)=(145-160)/(45-36)}}};
{{{m=-5/3}}}


In point-slope equation form, {{{y-180=-(5/3)(x-24)}}}
OR
two other possibilities equivalent to this one, since you are given two other points.
