<u>Corrected Question</u>
Suppose that y and z are points on a number line if yz equals 16 and y lies at -4. Where could z be located?
Answer:
z would be located at -4.
Step-by-step explanation:
If the product of y and z, yz=16
Point y lies at -4.
Substituting y=-4 into yz=16, we obtain:
Divide both sides by -4
Therefore, <u>z would be located at -4</u>, which is the same point at which y is located.
y and z are the same points on the number line.
We know our result is correct because the product of two negative numbers is positive.
