Answer:
y = 5x - 10
Step-by-step explanation:
If we take into account the parent function as the one that needs to be shifted and reflected then the new created function would be...
y = 5x - 10
This is because in order to reflect a function over the x-axis you need to multiply that function by -1. That being the case it would give us new function of
y = 5x - 8
Now in order to shift it down by 2 we simply need to subtract 2 from the function which would make is -10 since the 8 is a negative.
