The board is 12x larger in length than the nails. (Since the width of the board and nails are unknown, I am assuming you mean the length, not area difference)
If you want to find out your score if you did not step out of the boundaries, you need to add 0.3 + 9.124 = 9.424<span />
Answer:

Step-by-step explanation:
The line given has a slope of 7.5 and a point at (12, 80)
Because of the slope, simply subtract 2 from the x and subtract 15 from the y to get another point, at (10, 65)
Thus, simply put your points at (10, 65) and (12, 80)
Hope it helps and let me know if you want me to elaborate.
