Answer: 16 boxes and 6 football cards in each box.
Step-by-step explanation:
Here total football cards rob has = 96
And, He filled 9 boxes with basketball cards.
Also, Rob filled 3 fewer plastic boxes with football cards than basketball cards.
Therefore, football cards in each boxes = 9 - 3 = 6
Thus, the number of boxes he can fill with football cards = 96/6 =16
Answer:
y=-2+4
Step-by-step explanation:
we know the y intercept is four, so we can plug that into y=mx+b
so far we know y=mx+4
and the equation for finding slope is 
so let's find two points on the graph
let's make it easy on ourselves and use the points laid out for us
(0,4) and (2,0)
solving that would come out to be 
simplified, that would be -2
now that we know the slope, we can put them into slope-intercept form
y=-2+4
