Octagon abcdefgh and its dilation, octagon a'b'c'd'e'f'g'h', are shown on the coordinate plane below:

if the center of dilation is at the origin, by what scale factor was octagon abcdefgh dilated?

4
1/4
1/2
2

The answer is (c)

Step-by-step explanation: We are given the dilation of octagon ABCDEFGH which forms the octagon A'B'C'D'E'F'G'H' as shown in the given figure. Origin is the centre of dilation. We are to find the scale factor of the dilation.

We know that, to find the scale factor, we need to divide the length of one side of the dilated octagon A'B'C'D'E'F'G'H' by the length of the corresponding side of the original octagon ABCDEFGH.

Also, from the figure, we note that

GH = 4 units and G'H' = 2 units.

Therefore, the scale factor will be

Thus, (c) is the correct option.

assuming this is from a math graphing problem.

7 would be on the x-axis which is the horizontal line on the graph

84 would be on the y-axis which is the vertical line on the graph

17,000 is the correct answer.
