Question

a scatter plot was made to show the value of certain cars based on the age of the car in years. the equation of the scatter plots trend line is y = -1,700x + 32,000 where y is the value of the car in dollars, and x is the number of years since its been bought. what is the slope of the line of best fit? what does the slope mean in context? correct! the value of the car decreases by $1,700 per 1 year the value of the car increases by $1 per 1,700 years the value of the car decreases by $1 every 1,700 years

Explanation:

Step1: Recall the slope - intercept form of a line

The equation of a line in slope - intercept form is \(y = mx + b\), where \(m\) is the slope and \(b\) is the y - intercept.

Step2: Identify the slope from the given equation

Given the equation \(y=-1700x + 32000\), comparing it with \(y = mx + b\), we can see that \(m=-1700\).

Answer:

The slope of the line of best fit is \(-1700\).
