Question 1018257
Ordered pair are as  (p,A) for price p and attendance, A.


Two points described are  (11,100) and (6,1700).  You want to find the slope-intercept equation for the line containing these two points.


{{{A=mp+b}}}
{{{b=A-mp}}}
-
{{{m=(1700-100)/(6-11)=1600/(-5)=-320}}}
-
Pick either point...
{{{b=100-(-320)*11}}}
{{{b=100+320*11}}}
{{{b=3620}}}
-
{{{highlight(A=-320p+3620)}}}
