Diego started an exercise program in which each week he works at the gym between 4.5 and 6 hours and walks between 9 and 12 miles. make a graph to show the number of hours Diego works out at the gym and the number of miles he walks per week, list 3 possible combinations of working out and walking that meet Diego's goals

X = number of $4 stones

y = number of $6 stones

Ok, we know that she wants to give stones to at least 4 friends so we can set up our first inequality already:

x+y > = 4

(> = is greater than or equal to and < = is less than or equal to)

We also know she is restricted by the $30 dollar limit so we can set up the second inequality:

4x + 6y < = 30

With a little algebraic manipulation you can get them into the y=mx+b

y > = 4 - x

y < = 5 - 2/3x
