You would select the points with the x-values -3 and 2 and use the slope formula:
(-3, -36) and (2,4)
← slope formula
x1 = -3 y1 = -36 and x2 = 2 y2 = 4
(-3, -36) and (2,4)
x1 = -3 y1 = -36 and x2 = 2 y2 = 4
Answer:
Option D. 3 + 9i
Step-by-step explanation:
We know that the formula to find the middle point is:
We know that the middle point is:
And the end point is:
We wish to find the point
So we can write the following equation
(i)
and
(ii)
Now we clear from equation (i) and clear
from equation (ii)
For equation (i) we have:
For equation (ii) we have:
Then the initial point is:
The correct answer is the last option 3 +9i
