Write the coordinate rule with the given center and scale factor (k). Center: (6,2), k=3.5

The coordinate rule is

Explanation:

The center is given by

The scale factor is

We need to determine the coordinate rule with the given center and scale factor.

Let us consider the vertex as

The translation of the center is given by

Let us multiply the scale factor 3.5.

Thus, we have,

Simplifying the terms, we have,

Translating back, we get,

Simplifying the terms, we have,

Thus, the coordinate rule is

The answer is 7.21.
