Answer:
Step-by-step explanation:
Plot the points and connect in pairs.
We got a right triangle.
<u>The legs have the length:</u>
- 1 - (-2) = 3 units and
- 1 - (-3) = 4 units
<u>The area of the triangle is:</u>
- A = 1/2bh
- A = 1/2*3*4 = 6 square unit
X=9 mark as brainlest if this helps ;)
Add the real part and imaginary parts separately:-
answer is 7 + -8 + 3i + 9i
= -1 + 12i
You do 3-3=0 (it basically cancels each other out) then you do 12-3=9. So you have
Y=15x-9
