To find the rule that represents this function, we need to examine the pattern in the ordered pairs.
We can see that for each x-value, the corresponding y-value is obtained by multiplying the x-value by -4.
Therefore, the rule that represents this function is:
B. y = -4x
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?
A. y= x - 4
B. y= -4x
C. y=-4^x
D. y=x^-4
