Question

a freight company collects data on how many miles their truck drivers have traveled over varying periods of time. the company created a scatter plot and formally fit a line to the data using a graphing calculator. the screenshot shows the results of the company generating a line, in slope - intercept form, to model the relationship between the time spent driving, x, and the number of miles traveled, y.

statistics
$r^{2}=0.8787$
$r = - 0.9374$

parameters
$m = 0.906753$
$r=-4.45006$

complete the statements.
using the output shown, the equation for the line of best fit is

Explanation:

Step1: Recall slope - intercept form

The slope - intercept form of a line is $y = mx + b$, where $m$ is the slope and $b$ is the y - intercept.

Step2: Identify slope and y - intercept from given data

From the screenshot, the value of $m$ (slope) is $0.906753$ and the value of $b$ (y - intercept) is $- 4.45006$.

Answer:

$y=0.906753x - 4.45006$
