2+3i
------ should be multiplied (numerator and denominator both) by 2+i.  This will 
2-i        remove i from the denominator.

(2+3i)        2+i           4 + 2i + 6i - 3        1 + 8i
--------  * ----------- = ---------------------- =  ---------- (answer)
   2-i           2+i                   4+(-1)                8

You could also write this as (1/8) + i.

Answer:

y = -0.8x - 5

Step-by-step explanation:

x1 = (XA + XB) / 2 = -5

y1 = (YA + YB) / 2 = -1

m = (XA - XB) / (YA - YB) = -0

__________________________________________

(y - -1) = -0.8(x - -5)

y - -1 = -0.8x - 4

y = -0.8x - 4 + -1

y = -0.8x - 5
