The points (2,10) and (minus2,minus10) are plotted on the coordinate plane using the equation yequalsatimesx. How can you use the coordinates to find the value of a? Select the correct answer below, and fill in the answer box to complete your choice. (Type a whole number.) A. The value of a is the number that the y-values are multiplied by to get to the corresponding x-values. So, aequals nothing. B. The value of a is the absolute value of the difference of the y-values. So, aequals nothing. C. The value of a is the number that the x-values are multiplied by to get to the corresponding y-values. So, aequals nothing. D. The value of a is the absolute value of the difference of the x-values. So, aequals nothing.
