Answer:
4+i
Step-by-step explanation:
A complex number usually took the form a+bi where a and b are real numbers and 'i' represents an imaginary number. For a quadratic equation, the complex roots for the root of a quadratic equation took the form known as complex conjugates. The complex conjugates are formed by changing the sign of the imaginary part.
SO, if a quadratic equation has 4-i as a solution, the other solution must be 4+i.

Answer:
y = -4x + (any number)
Step-by-step explanation:
you want to use the negative reciprocal of the slope for line f
so m = -4, since you didn't say any points it has to go through then the 
equation of the line is y = -4x + (any number)
