Answer:
I think 4^0 is the answer
1) y= 2/5x -3
2) y= 2/3x + 1
3) y= 2x -1
4) y= 5/4x + 3
I think
The distances in length and height and the total have the same unit (e.g. feet or meters). When the slope is decreasing, height and slope have a minus as prefix.
Example: a road with 15% slope has an angle of 8.58°. At a length of 200 feet, a height of 30 feet and a total distance of 202.24 feet is covered. Total Distance, Length and Height.
A.) 3 4/8 or 1 2/10
B.) 2 14/8 or 12/10
