Answer: The slope is 25. Y intercept is 100
Step-by-step explanation: Using y2-y1/x2-x1 just enter in any two x and y coordinates you want. For example...
1. (10, 350) and (20, 600)
2. 600-350/20-10
3. 250/10
4. Simplifies to 25.
1. Plug the points into y=mx+b
2. 350=25(10)+b
3. 350-250=250-250+b
4. 100=b
I think the current age of the child is 16 and the father is 40. That would mean 4 years ago the father was 36 and the child was 12. This makes the father 3 times as old as his son four years ago.
