Answer:
a
Step-by-step explanation:
The best answer is A. The possible roots of this polynomial function 9i and -9i. It is possible that this polynomial function is a quadratic equation. It has a degree of two which means there are two roots and it is possible that the positive and negative value of 9i are its roots.
The slope of a line between 2 points is given by the formula
m = y2 - y1/x2 - x1
m= 22-6/20-12
m= 16/8= 2
slope is 2
