The Jackson family rents 6 movies each month. Draw a graph of movies rented versus time. Find the value of the slope and interpr

atroni [7]

Let us say "y" coordinate represents number of movies and "x" coordinate represents number of months.

Movies watched in 1st month = 6

so we can say first ordered pair is (1,6)

Movies watched in 2nd month =6

so we can say second ordered pair is (2,6)

Now we have two points here (1,6) and (2,6)

We can use formula for slope as :

$slope = \frac{y2-y1}{x2-x1}$

$slope = \frac{6-6}{2-1}$

slope = 0

The slope of a horizontal line. A horizontal line has slope 0 because all its points have the same y-coordinate. As a result, the formula used for slope evaluates to 0.

The graph is shown here:

The equation of graph would be y=6.

How do you find the r?

Anna35 [415]

Use the formula (zy)i = (yi – ȳ) / s y and calculate a standardized value for each yi. Add the products from the last step together. Divide the sum from the previous step by n – 1, where n is the total number of points in our set of paired data. The result of all of this is the correlation coefficient r.

Y = -0.4x +0.3 in standard form using integers !!!!

Reptile [31]

Add 0.4x
$y + 0.4x = 0.3$
Multiply by 10
$10y + 4x = 3$
