Question

Solve the problems using your graphing calculator. Round all parameter values to

Answer 1

Drawing a scatter plot for the given values on a graphing calculator, we have;

• y = -0.19•x + 8.36

How can the function that best represents the data be found?

The values are;

Day; Running time

1; 8.2

2; 8.1

3; 7.5

4; 7.8

5; 7.4

6; 7.2

7; 7.1

Entering the above values in a graphing calculator, we have;

• The slope of the line of best fit = -0.19
• The x-intercept = 45

Therefore;

• 0 = -0.19 × 45 + y-intercept

0 = -8.36 + y-intercept

• y-intercept = 8.36

The equation found using the statistics function for scatter plot on a calculator is therefore;

• y = -0.19•x + 8.36
