How is the product of a complex number and a real number represented on the coordinate plane?

a. When 6 + 4i  is multiplied by 3, the result is 18 + 12i. Graphically, this shows that the product is a scalar and a 90° counterclockwise rotation of the complex number.

 

b. When 6 + 4i  is multiplied by 3, the result is 18 + 12i. Graphically, this shows that the product is a scalar of the complex number.

 

c. When 6 + 4i  is multiplied by 3, the result is 18 + 12i. Graphically, this shows that the product is a scalar and a 90° clockwise rotation of the complex number.

 

d. When 6 + 4i  is multiplied by 3, the result is 18 + 12i. Graphically, this shows that the product is a 90° counterclockwise rotation of the complex number.
