X difference: 7-2 = 5
y difference: 11-10 = 1
Add up those results: 5+1 = 6

Step-by-step explanation:

Answer:
3
Step-by-step explanation:
It is rotated 90 degress clockwise then reflected across the x-axis
For there to be an infinite number of solutions, the quantity on the left side of the equation must be the same as on the right.
First, distribute the equation to get
6x + 18 = 3xh + 9h
If h = 2, the equation on the right would also be 6x + 18 which would yield the same equation and hence an infinite number of solutions
So the answer is h = 2
