Answer:
y = - x +
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, - 3) and (x₂, y₂ ) = (- 1, 4)
m = =
= -
, thus
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, 4), then
4 = + c ⇒ c = 4 -
=
y = - x +
← equation of line
The correct answer from the choices given will be -13 - 4i. The numerical part is the real number while the term containing i is the imaginary part.
<h3>What is the complex number?</h3>
A complex number is one that both a real and an imaginary component, both of which are preceded by the letter I which stands for the square root of -1.
The given complex number as;
By transfeering the left-hand side term to the right-hand side the sign will change. We will get the value of n as;
Hence the correct answer from the choices given will be -13 - 4i.
