What does linear mean?

California Government discovered the recent wildfires are causing the number of trees to decrease in the Yosemite National Park. The number of trees was approximately 100,000. The number of trees is decreasing at an average rate of 0.03 tree per week.

Which function can be used to find the number of trees in x weeks since the discovery?

• $t\left(x\right)=-0.03\left(x+100,000\right)$

• $t\left(x\right)=100,000+0.03x$

• $t\left(x\right)=0.03\left(x+100,000\right)$

• $t\left(x\right)=100,000-0.03x$
