The points ​(3​,9​) and ​(-3​,-9​) are plotted on the coordinate plane using the equation yax. How can you use the coordinates to find the value of​ a? A. The value of a is the absolute value of the difference of the​ y-values. So, a= nothing.
B. The value of a is the number that the​ y-values are multiplied by to get to the corresponding​ x-values. So, a= nothing.
C. The value of a is the absolute value of the difference of the​ x-values. So, a= nothing.
D. The value of a is the number that the​ x-values are multiplied by to get to the corresponding​ y-values. So, a=
