The table represents a function.
x : 0, 2, 4, 6,
y : 6, 8, 10, 12,
complete the statement by choosing a, b, or c
the rate of change in the function y = x + 4 is ? the rate of change of the function represented in the table.
a) greater than
b) less than
c) equal to
replace the question mark in the sentence above with a, b, or c

"Rate of change" is another name for "slope".

In the table, every time 'x' increases by 2, 'y' also increases by 2.
So the rate of change (slope) of the function in the table is

         (change in 'y') / (change in 'x')  =  2/2  =  1  .

The rate of change (slope) in the function  y = x + 4  is
the coefficient (number before) the 'x'.  That's also ' 1 '.

So the rate of change in the function y = x + 4 is the same as (equal to)
the rate of change of the function represented in the table.
