SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Write the growing rate of the first tree
Tree 1 is growing 1.5 inches every week
STEP 2: Calculate the growing rate of the second tree
This implies the slope and is calculated using the formula;
![m=(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2023/formulas/mathematics/high-school/78uaqhwt0aws3qfwxigaftpihnmb1gzxtp.png)
By substitution,
![m=(5-4)/(2-1)=(1)/(1)=1](https://img.qammunity.org/2023/formulas/mathematics/college/2xhgw8zxyw74kmsxicadt4wl5rcnez1fhl.png)
The slope of 1 means that Tree 2 is growing at a rate of 1 inch per week
Hence, the tree that is growing faster is Tree 1 with a rate of 1.5 inches per week
ANSWER:
Tree 1
