<h2>Answer:</h2>

option: B is the correct answer.

                   B. complex numbers.

<h2>Step-by-step explanation:</h2>

We know that a complex number is always written in the form of :

                                 a+ib

  where a and b are real numbers and i is the square root of -1.

i is called an imaginary number.

If a>0 and b>0 then the point lie in the first quadrant.

if a>0 and b<0 then the point lie in the fourth quadrant.

if a<0 and b>0 then the point lie in the second quadrant.

if a<0 and b<0 then the point lie in the third quadrant.

Find the distance from the point (4,2) to the line y= −2.
riadik2000 [5.3K]

Answer:

The distance is 4.

Step-by-step explanation:

The shortest distance from the point (4,2) to the line y=-2, in this case, would be a straight line perpendicular to y=-2.

For each and every value of "x" on the line, y = -2. The shortest distance occurs at y(4) = - 2.

At this point the distance is:

d^{2} =(4 - 4)^{2} + (2-(-2))^{2} \\d^{2} =4 ^{2}\\\\d = 4

The distance is 4.
