Answer:
The scale factor is
Step-by-step explanation:
Line segmentAB has vertices A(−3, 4) and B(1, −2) .
A dilation, centered at the origin, is applied to AB. The image has vertices
A'(-1,4/3) and B′(1/3, −2/3) .
We know the rule for dilation by scale factor of k, is
This means that;
But we know, A' has coordinates (-1,4/3)
This means that
We could also compare:
4k=4/3
Which gives
k=⅓
Answer:
see below
Step-by-step explanation:
The points at the corners of the given figure are ...
(0, 0), (0, 4), (3, 4), (3, 0)
When the figure is scaled by a factor of 1/3, each of the coordinates is multiplied by 1/3:
(0, 0), (0, 4/3), (1, 4/3), (1, 0) . . . . . points scaled by 1/3
When the figure is scaled by a factor of 3/2, each of the coordinates is multiplied by 3/2:
(0, 0), (0, 6), (9/2, 6), (9/2, 0) . . . . . . points scaled by 3/2
