Alternate means it will be across and on the opposite side, there for the alternate interior angle for 2 would be the same number as the function you're solving.
For example: if you're going to find the alternate interior of 17x+9, it will be 17x+9, the angle on the lower right hand side of the top parallel line.

Find the number of light years
-------------------------------------------------------------------------------------

$\text {Number of light years = } \dfrac{6.8 \times 10^{13}}{9.46 \times 10^{12}}$

$\text {Number of light years = } 7.18$

-------------------------------------------------------------------------------------
Answer: The distance from Earth to the star is 7.18 light-years.
