I was able to determine the rule because line c has a slope (m) of 1 (it goes up one and sideways one each time). Its y int. is at 3, so that means 3 is b in the equation y= mx+b
Rule for line D: y=1/2x
x y
0 0
2 1
4 2
6 3
Line d is y=1/2x becaise it goes up 1 and then sidewys 2, so slope (m)= 1/2. There is no b becase it crosses the origin.
(-2,-1) (-4,-2) (-6, -3) just extend the line with a ruler.
