Q. Use the given verices to calculate the coordinates of △LMN after a dilation centered at the origin with scale factor k=−3.L(0,0),M(−4,1),N(−3,−6)
Understand Dilation Effect: Understand the effect of dilation with a negative scale factor. Dilation with a scale factor of k=−3 means that each vertex of the triangle will be scaled by a factor of 3 and reflected across the origin because the scale factor is negative.
Apply Dilation to Vertex L: Apply the dilation to vertex L(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)
Apply Dilation to Vertex M: Apply the dilation to vertex M(−4,1). Multiply each coordinate of M by the scale factor −3. M′=(−4×−3,1×−3)=(12,−3)
Apply Dilation to Vertex N: Apply the dilation to vertex N(−3,−6). Multiply each coordinate of N by the scale factor −3. N′=(−3×−3,−6×−3)=(9,18)
