Question

sketch the ray of best fit for the following scatterplot: use the graph provided above to determine the slope and the y - intercept for the relationship. you may round to the nearest integer. m:

Explanation:

Step1: Identify two points on the ray

We can see the ray passes through (0, 800) (the y - intercept) and another point, say (400, 2400) (from the graph, when x = 400, y = 2400).

Step2: Calculate the slope

The formula for slope \( m=\frac{y_2 - y_1}{x_2 - x_1} \). Let \((x_1,y_1)=(0,800)\) and \((x_2,y_2)=(400,2400)\). Then \( m=\frac{2400 - 800}{400 - 0}=\frac{1600}{400}=4 \).
