Answer:

#x<7/2# or #x<3.5#

Plot the graph of x=3.5 with dotted line and shade the area of #x# less then 3.5 as shown in the attached graph.

Explanation:

solving for #x# by making #x# the subject of the equation:

#2x+9<16#
#2x<16-9#
#2x<7#
#x<7/2# or #x<3.5#

graph{x<3.5 [-10, 10, -5, 5]}

Plot the graph of x=3.5 with dotted line and shade the area of #x# less then 3.5 as shown in the attached graph.
