Which equation could have been used to create this function table?

a.
y = x + 4

b.
y = x + 3

c.
y = 4x

d.
y = 6x

The answer is B.

Example:

Plug in for x. 

       x        |         y

1               |        4  
3               |        6
7               |       10
9               |       12
11             |       14

Equation: y = x + 3.

y = 1(plug in x) + 3 = 4 which is y.

y = 3 + 3 = 6 which is y.

y = 7 + 3 = 10 which is y.

y = 9 + 3 = 12 which is y.

y= 11 + 3 =14 which is y.

Equation y = x + 3

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"
