Answer: (10/4, -28/4)
Step-by-step explanation: Use the distance formula to find the distance between the two points and then partition it into 4ths to get the ratio of 3:1. You will get that every 4th is √65/2, we then multiply this by 3 and find the point that is that distance away from -8,-1 with the same slope. We get (10/4, -28/4)
