Question

What are the slope and the y-intercept of the line of best fit on this scatter plot?

Answer 1

Answer:

A. The y-intercept is 8 and the slope is $-\frac{4}{3}$.

Step-by-step explanation:

We have been given graph of line of best fit. We are asked to find the y-intercept and slope of our given line.

We know that y-intercept of a graph is the point, where line intersects y-axis. upon looking at our given graph, we can see that our line touches y-axis at point (0,8), therefore, y-intercept is 8.

Let us find slope of our given line using points $(0,8)\text{ and }(6,0)$ as:

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{0-8}{6-0}$

$m=\frac{-8}{6}$

$m=-\frac{4}{3}$

Therefore, the slope of our given line is $-\frac{4}{3}$ and option A is the correct choice.
