Mrs. Jackson gives the table below to her students.
$x$$y$
426
523
6$a$
In order for the function to be linear, what must $a$ be and why?
A$a=22$ because the rate of change is 1.
B$a=20$ because the rate of change is 3.
C$a=22$ because the rate of change is -1.
D$a=20$ because the rate of change is -3.
$x$ | $y$ |
4 | 26 |
5 | 23 |
6 | $a$ |
A$a=22$ because the rate of change is 1.
B$a=20$ because the rate of change is 3.
C$a=22$ because the rate of change is -1.
D$a=20$ because the rate of change is -3.
