The answer is the 3rd option
Answer:

Step-by-step explanation:
Refer the attached figure .
We are given a line AB
Point A
Point B
Formula for slope 'm' when two points are given :

Substituting thew values


Since we are given that AB is perpendicular to BC
So, By property - perpendicular slopes are negative reciprocals of each other.



So, Slope for line BC : 
Point B = (4,4)
Formula of equation of line : 





Hence the equation of line BC : 
Answer:
Option B
Step-by-step explanation:
Let the point O is the origin.
Then the coordinates of the vertices A,B and C will be,
A → (-12, -8)
B → (-8, 0)
C → (-6, -4)
Rule for the dilation of a point (x, y) by scale factor 'k' about the origin is,
(x, y) → (kx, ky)
By this rule, coordinates of the vertices of the image triangle will be,
If k =
,
A(-12, -8) → A'(-6, -4)
B(-8, 0) → B'(-4, 0)
C(-6, -4) → C'(-3, -2)
From the given options,
Option B is the answer.
