Question

Suppose you are told that the number of X Station gaming consoles increased linearly for the month of December. What can the slope of the linear regression tell us about the trend for the number of X station gaming consoles sold?

Answer 1

It could tell you that your amount sold is going up steadily per unit of time

Answer 2

Answer:

$m=\frac{XStationSold}{Time}$

Step-by-step explanation:

The slope (m) is a number that describes both the direction and the steepness of the line and it can be calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line (rise over run). In our case the vertical change (change in y or rise) wil be the amount of consoles sold and the horizontal change (change in x or run) will be the days of the month of december(i.e. x consoles per day). Like this

$m=\frac{XStationSold}{Time}$
