Answer:

#b < 6.5#
Draw a number line and mark everything to the left of #6.5# as included in the solution set.

Explanation:

Given #b-4 < 2.5#

You can add the same amount to both sides of an inequality without effecting the orientation of the inequality.

So, by adding #4# to both sides we get
#color(white)("XXXX")##b < 6.5#
