Question 306684
Ok I need another intersection again. 
For graph the inequalities 9x+8y<72 ans -7x-44<=28 
-----------------------------------------------------
Graph 9x+8y<72
{{{graph(400,300,-10,10,-10,10,y < (-9/8)x+9)}}}
---------------------------
Graph -7x-44<= 28
Note: Your post did not contain a "y" so you get a one-dimensional graph:
x >= (-44/7)-4
------------------------
Cheers,
