Answer:
y = x+
Step-by-step explanation:
Okay, the first thing to do here is calculate something known as the "slope".
We know two points are ( 1 , 5 ) and ( − 2 , 3 )
The slope is represented by "m" in the standard form: y = mx+b
The slope is also known as the rise over the run, y2-y1/x2-x1 = =
=> the standard form: y = x+b
Now we have to use the slope, and resubstitute another point to get b
5 = (1) + b
<=> b= 5- =
So the equation that model the line is: y = x+
Answer:
Step-by-step explanation:
The modulus is the magnitude of the complex number; the argument is its angle (usually in radians).
__
<h3>rectangular form</h3>The complex number can be cleared from the denominator by multiplying numerator and denominator by its conjugate:
The magnitude of this number is the root of the sum of the squares of the real and imaginary parts:
modulus = √((-3)² +(-3)²) = 3√2
The argument is the arctangent of the ratio of the imaginary part to the real part, taking quadrant into consideration.
arg = arctan(-3/-3) = -3π/4 or 5π/4 . . . . radians

modulus∠argument = (3√2)∠(-3π/4)
