Answer:
-8i + 12
Step-by-step explanation:
-4i(2 + 3i) = -8i - 
= -8i - 12 * (-1) = -8i + 12
We have two points so we can find the gradient using y1-y2/x1-x2
gradient = 21-27/2-8
= 1
we know the form for any linear equation is y = mx + c
we have m and a point so we can substitute in point (2,21) to find c
21 = 1 x 2 + c
c = 19
therefore, the equation is y = x + 19
