Answer:
Henry could only see one line.
Step-by-step explanation:
Since, both line have same slope. The graph of both equation will be same and hence it will overlap each other.
The way you could find slope is to use y1-y2 dived by x1-x2. So you would be given to point like (3,5) and (2,4). You would just put the numbers in where they belong so the 5 could be y1 and the 4 could be y2. Then 3 would be x1 and 2 would be x2.
