The ordered pairs (1,-4). (2, -8). (3,-12), (4.-16) and (5.-20) represent a function. What is a rule that represents this function?
To find a rule that represents this function, we can look for a pattern in the ordered pairs.
If we observe the x-values, we can see that they increase by 1 each time: 1, 2, 3, 4, 5.
If we observe the y-values, we can see that they decrease by 4 each time: -4, -8, -12, -16, -20.
Therefore, we can conclude that the rule that represents this function is:
y = -4x
