Math Problem Statement
Rectangle ABCD is shown on the coordinate plane below. If a dilation image of Rectangle ABCD with the origin as the center of dilation and a scale factor of 2, which ordered pair would NOT be a vertex of this dilation?
Solution
The problem asks for the ordered pair that would NOT be a vertex after dilation of rectangle ABCD, centered at the origin, with a scale factor of 2.
Step 1: Identify original coordinates of ABCD
Looking at the grid, we can estimate the coordinates of each vertex of rectangle ABCD:
Step 2: Apply dilation
The dilation formula with the origin as the center and a scale factor of 2 is: Apply this to each vertex:
Step 3: Check options
Now compare the given options:
- (10, -2) → Not a vertex
- (-2, 2) → Not a vertex
- (-2, 10) → Not a vertex
- (10, 10) → Not a vertex
None of these match the vertices after dilation.
