The coordinates of the vertices of triangle LMN are L (4, -4), M (2, 6), and N (8, 2). Triangle LMN is dilated by a scale factor of 5/2 with the origin at the center of dilation to create triangle L'M'N'. If (x, y) represents the location of any point on triangle LMN, which ordered pair represents the location of the corresponding point on triangle L'M'N'?​ (a)  

• (5/3x, 5/3y)
• (2/5X, 2/5Y)
• (X+5/3, Y+5/3)
• (X+2/5, Y+2/5)
