Answer:
New coordinate of A will be (12, 18).
Step-by-step explanation:
Coordinates of origin (0, 0) are fixed and the points A(6, 9) and B(6, 0) are multiplied by 2.
Rule for the dilation of the sides of the triangle by the scale factor of 2 about the origin is,
A(x, y) → A'[2(x, y)]
Following this rule for dilation new points will be,
A(6, 9) → A'(12, 18)
B(6, 0) → B'(12, 0)
Therefore, new coordinates of A will be (12, 18).
