To find the coordinates of the new vertices \(E'F'G'H'\) of the parallelogram after dilation with a center at the origin and a scale factor of 3, we need to multiply the coordinates of each vertex by the scale factor.
If the original coordinates of the vertices are:
- \(E(2, 8)\)
- \(F(-1, 5)\)
- \(G(4, 4)\)
- \(H(1, 1)\)
Then, the coordinates after dilation (using the formula \((x, y) \to (kx, ky)\) where \(k\) is the scale factor) will be calculated as follows:
- \(E' = (3 \cdot 2, 3 \cdot 8) = (6, 24)\)
- \(F' = (3 \cdot -1, 3 \cdot 5) = (-3, 15)\)
- \(G' = (3 \cdot 4, 3 \cdot 4) = (12, 12)\)
- \(H' = (3 \cdot 1, 3 \cdot 1) = (3, 3)\)
So the new vertices after dilation will be:
- \(E'(-3, 15)\)
- \(F'(6, 24)\)
- \(G'(12, 12)\)
- \(H'(3, 3)\)
Thus, the correct response is: E′(−3,15), F′(6,24), G′(12,12) and H′(3,3).
