Question

tran has made a plan to help him study for his math exam.
he has broken the material that he has study into two parts. Part a and part b and has, at most 2 hours every evening to over the next week to study.
he wants to spend at least twice as much time studying for part a as for part b.

how do I graph this on graph paper?

Answer 1

graph the lines
(a) a+b = 2
(b) a = 2b
You will see a triangle, with the axes and line (a) above as its boundaries.
Any (a,b) values inside that triangle will satisfy the requirements.
