Common differences among the
x
-values and
y
-values and determine if they represent a linear function.
{(3,0),(6,3),(9,6),(12,9)}
x
- values:
6-3=3,9-6=3,12-9=3
y
- values:
3-0=3,6-3=3,9-6=3
It is a linear function.
x
- values:
6+3=9,9+6=15,12+9=21
y
- values:
3+0=3,6+3=9,9+6=15
It is a linear function.
x
- values:
6-3=3,9-6=3,12-9=3
y
- values:
3-0=3,6-3=3,9-6=3
It is not a linear function.
x
- values:
6+3=9,9+6=15,12+9=21

- values:
3+0=3,6+3=9,9+6=15
It is not a linear function.
6) Find the common differences among the
x
-values and
y
-values and determine if they represent a linear function.
{(-2,-5),(-5,-11),(-8,-17),(-11,-20 )}
x
- values:
-5-(-2)=-3,-8-(-5)=-3,-11-(-8)=-3
y
- values:
-11-(-5)=-6,-17-(-11)=-6,-20-(-17)= -3
It is a linear function.
x
- values:
-5+(-2)=-7,-8+(-5)=-13,-11+(-8)=-19
y
- values:
-11+(-5)=-16,-17+(-11)=6,-20+(-17)= -37
It is a linear function.
x
- values:
-5+(-2)=-7,-8+(-5)=-13,-11+(-8)=-19
y
- values:
-11+(-5)=-16,-17+(-11)=6,-20+(-17)= -37
It is not a linear function.
x
- values:
-5-(-2)=-3,-8-(-5)=-3,-11-(-8)=-3
y
- values:
-11-(-5)=-6,-17-(-11)=-6,-20-(-17)= -3
