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;
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
By substitution,
[tex]m=\frac{5-4}{2-1}=\frac{1}{1}=1[/tex]
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
