your club is baking strawberry and apple pies for a bake sale. They need at most 18 pies, and cannot have more than 12 apple pies. Write and graph a system of inequalities to model this system.

Answer 1

s + a < /= 18
a < 12
call vertical (y) axis s
call horizontal (x) axis a
then
s+a = 18 slopes down at slope = 1 from (0,18) to (18,0)
need to be below or on it
a = 12 is a vertical line at 12
need to be on or to the left of it
so your shaded region is below the slanted line and left of the vertical one
