Question

PLEASE HELP IM DESPERATE !,The t-chart below shows the length of a vine x days after it is planted. Answer the following questions. 1. What is the slope-intercept form of the function that can be used to model the length of the vine after x days? 2. Based on the model, what is the predicted length of the vine after 53 days? Be sure to show all work and answer in complete sentences. Days Length (cm) 5 3 10 8 15 13 20 18​

Answer 1

Considering the data given in the table, we have that:

1. The regression line is: y = x - 2.

2. The predicted length after 53 days is of 51 cm.

How to find the equation of linear regression using a calculator?

To find the equation, we need to insert the points (x,y) in the calculator.

In this problem, the points are:

(5,3), (10,8), (15, 13), (20,18).

Hence, inserting them into the calculator, the equation is:

y = x - 2.

Hence, after 53 days, the length in cm is given by:

y = 53 - 2 = 51 cm.
