Answer:
a) non-proportional/ constant rate: 3
b) non-proportional/ constant rate 3
Step-by-step explanation:
y=-4x+3
as x=0
put in y= -4x+3
y= -4(0)+3
y=3
now put x=1 in y= -4x+3
y= -4(1)+3
y= -1
now put x=2 in y= -4x+3
y= -4(2)+3
y=-5
well, there are 100 marbles
there are 35 and 15 already known which equals to 50
therefore 50% of the bag is black marbles
