Triangle QRS has been dilated to create triangle Q'R'S'. Which is the scale factor of the dilation? A graph with x-axis labeled from negative 6 to 6. The y-axis is labeled from negative 6 to 6. Three points labeled Q, R, and S form a triangle. Three points labeled Q', R', and S' from a larger triangle. Q is at (0, 1). R is at (1, -1). S is at (-1, -1). Q' is at (0, 4). R' is at (4, -4). S' is at (-4, -4).
