Q. Use the given verices to calculate the coordinates of LMN \triangle L M N after a dilation centered at the origin with scale factor k=3 k=-3 .\newlineL(0,0),M(4,1),N(3,6) L(0,0), M(-4,1), N(-3,-6)
  1. Understand Dilation Effect: Understand the effect of dilation with a negative scale factor. Dilation with a scale factor of k=3k=-3 means that each vertex of the triangle will be scaled by a factor of 33 and reflected across the origin because the scale factor is negative.
  2. Apply Dilation to Vertex L: Apply the dilation to vertex L(0,0)(0,0). Since L is at the origin, and dilation centered at the origin will not change its position, regardless of the scale factor. L=(0×3,0×3)=(0,0)L' = (0 \times -3, 0 \times -3) = (0, 0)
  3. Apply Dilation to Vertex MM: Apply the dilation to vertex M(4,1)M(-4,1). Multiply each coordinate of MM by the scale factor 3-3. M=(4×3,1×3)=(12,3)M' = (-4 \times -3, 1 \times -3) = (12, -3)
  4. Apply Dilation to Vertex NN: Apply the dilation to vertex N(3,6)N(-3,-6). Multiply each coordinate of NN by the scale factor 3-3. N=(3×3,6×3)=(9,18)N' = (-3 \times -3, -6 \times -3) = (9, 18)
