x=5
Yes it is proportional. You multiply x by 1 to get y.
CP = 1
x=14.2
y=1x or y=x
y= 1/10 x or y=0.1x
There isn't one. None.
the line must be straight and it must go through the origin
4 or 4:1
x=4.4
change 0 to 1/2 OR change 1 to 0
y=1/45x
y= 4/9 x or y=0.44x
CP = 1/10 or 0.10
CP= 4/9 or 0.44
change 65 to75 OR change 15 to 13
y=1/30x
2 or 2:1
24.11 or 24.11:1
8.67 minutes per mile
48 cookies per hour
x=30
(3,1) OR (6,2) OR (9,3) etc...
CP = 1/3
x=1
