Answer:
<h2>19 + 0i</h2>
Step-by-step explanation:

Since the straight line has a negative slope and passes therough the first, second and fourth quadrants, the value of y when x = -3 will be a positive number greater than 3.
Therefore, the correct answer is option A (y = 4)
<span>Exponents are the repeated multiplication of a
number. It is represented by the formula of a^n where a is the number to be
repeated and n is the number of times the number is being multiplies by itself.
Also include the sign of the number, no matter how it is multiplied, it is
still important. In this problem, you have 4 as the repeated number. You can
see that it is multiplied by itself by two times. So you have (-4)^2.</span>
