we can mark points on the graph shown , check the image I have shared with this for the points .
Formula for slope = 
So for Line A points are (1,3) and (0,-1)
So using t he formula slope is = 
slope of line A =4
For Line B the points are (0,4) and (3,-5)
So using t he formula slope is = 
slope of line B = -3
You need to do length•width•height.
Replace x with 2+i and solve
Remember that i is the square root of -1
My phone automatically capitalizes I, so don’t be confused by that!
y=(2+I)^2 + 3(2+I) +5
y=4+4i-1+6+3i+5
y=7i+14
