Using the slope of a linear function, it is found that Tree 1 is growing faster.
What is a linear function?
A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1. It can be given by the change in the input divided by the change in the output.
- b is the y-intercept, which is the value of y when x = 0.
In this problem:
- Tree 1 is growing 1.5 inches every week.
- For tree 2, when the week increasing by 1, the height also increases by 1, hence the slope is 1, which means that it is increasing 1 inch per week.
- Thus, tree 1 is growing faster.
