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
