The smaller triangle is a dilation of the larger triangle with a center of dilation at (2,−1). What is the scale factor of the dilation? 13 12 2 3 Coordinate plane. The horizontal axis ranges from negative 6 to 4 in increments of 1. The vertical axis ranges from negative 3 to 7 in increments of 1. Two triangles are on the coordinate plane. The vertices are not labeled. Both triangles share a vertex at the point 2 comma negative 1. The smaller triangle also has vertices at points two comma two and negative one comma negative one. The larger triangle also has vertices at points two comma five and negative four comma negative one.
