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.
Answer:
(3, -2)
Step-by-step explanation:
Find the midpoint coordinates (x, y) of points A(2, - 5) and B(4, 1)
x-coordinate of the midpoint is (2+4)/2 = 6/2= 3
y-coordinate of the midpoint is (-5+1)/2 = -4/2= -2
The mid point coordinates are (3, -2)
