Question

Help me with number 6 please!!!

Answer 1

Hints:  in 5x+4y=32, let x= to obtain the y-intercept.  y=8.  This is the UPPER limit of the visible window.  Next, let y= 0 in this same equation, to obtain the x-intercept.  Answer:  x=32/5.  Since the 2 graphs extend beyond x=32/5, to the right, adopt x=7 as the RIGHT HAND limit of the visible window.  Can you finish this problem?
