Answer:
y=-1/5x-16/15
Step-by-step explanation:
slope intercept form y=mx+b
3x+15y=-16
15y=-3x-16 divide both sides by 15
y=-3/15x-16/15 simplify -3/15 to -1/5
y=-1/5x-16/15
The answer is 40
you just times 23 by the number of photocopies you need with is 20
so 23x20 which is 460
500-460 is 40
6:10 or 3:5 I believe
Hope this helps!
