Strategy
Light Strike Array destroys trees which can be useful against certain heroes.
Make use of Lina's long attack range to harass opponents in the lane frequently.
Use Light Strike Array when opponents are somewhat stationary, e.g. when they are going for a last hit or deny.
Dragon Slave is great for securing ranged creep last hits and harassing opponents at the same time.
Use Dragon Slave on creep waves to maintain Fiery Soul Stacks and keep your maximum damage potential in fights and for farming.
Lina is great at split pushing with her quick wave clear abilities, as well as pick offs due to her high movement speed and massive burst damage.
Keep fiery soul stacks up in fights to ensure you dish out your maximum DPS with right clicks.
With your 
Aghanim's Scepter pick up, you can fly over treelines and cliffs to find better initiation angles or escape.
Pick up 
Aghanim's Shard after your first few core items to gain a massive damage barrier on Laguna Blade usage and survive in fights. Look to start fights with Laguna Blade where the Light Strike Array stun isn't necessary.
Counter Strategy
Lina's Light Strike Array has a long cast point. Look to dodge it.
Lina is a glass cannon type hero. Look to focus her in the fights.
Magic resistance and spell immunity items are great against Lina.
Gap closing items are good at getting you on top of Lina.
Lina is great at split-pushing and ratting. Consider getting 
Boots of Travel on a core.
