Slick Slack is a downloadable app that can be used to automatically generate excuses for being late to work based on the weather

Greeley [361]

Answer:

$(x_1,y_1) = (1,5840)$

$(x_2,y_2) = (2,13090)$

$y = 1812.5x + 4027.5$

$y_0 = 4027.5$ --- y intercept

Step-by-step explanation:

Given:

x = weeks; y = copies

The right parameters are:

After 1 week, 5840 copies were downloaded

After 5 weeks, 13090 copies were downloaded

So, the (x,y) forms are:

$(x_1,y_1) = (1,5840)$

$(x_2,y_2) = (5,13090)$

Next, we calculate the slope (m) using:

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

$m = \frac{13090 - 5840}{5 - 1}$

$m = \frac{7250}{4}$

$m = 1812.5$

The equation is then calculated using:

$y = m(x - x_1) + y_1$

$y = 1812.5(x - 1) + 5840$

$y = 1812.5x - 1812.5 + 5840$

$y = 1812.5x + 4027.5$

To calculate the y intercept, substitute 0 for x

$y_0 = 1812.5*0 + 4027.5$

$y_0 = 0 + 4027.5$

$y_0 = 4027.5$
