Answer:
A.
Step-by-step explanation:
Multiplying by moves the decimal point n places to the right.
Doing so 8 times for 5.21 gives 521,000,000.
Y=mx+b
b=y intercet or wwhere the line intercepts the y axis
you want this to be negative so it will be les than zero so cross out any answer with b is positive
its decreaseing so therefor the slope is negative
the answer is the third on which is y=-1/9-5
Answer:
I know it’s going to be -5 and -1.3 but I’m not sure about the zero I don’t know if you count zeros to but please let me know.
