Question

sketch the line of best fit for the following scatterplot:
use the graph provided above to determine the slope and the y - intercept for the relationship. provide the slope as a fraction or a decimal accurate to the nearest tenth.
m:

Explanation:

Step1: Identify two points on the line

From the graph, we can take two points: let's use (0, 800) (the y-intercept) and (600, 0) (the x-intercept).

Step2: Calculate the slope

The slope formula is $m = \frac{y_2 - y_1}{x_2 - x_1}$. Substituting the points $(x_1, y_1) = (0, 800)$ and $(x_2, y_2) = (600, 0)$:
$m = \frac{0 - 800}{600 - 0} = \frac{-800}{600} \approx -1.3$ (rounded to the nearest tenth)

Answer:

-1.3
