complex numbers can be graphed on the xy coordinate plane.
true
false

The standard form of an imaginary number is a ± bi where a is the real number and b is the imaginary number. The answer hence is false. i related to an imaginary number is equal to square root of -1. Hence when i is squared, the answer should be -1. Answer is false. Complex numbers can be graphed only in an plane with an imaginary axis and a real axis/ Answer in 3 is false
