Answer:
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).

Answer: -5/12
Step-by-step explanation: Before multiplying two fractions together by multiplying across their numerators and multiplying across their denominators, you should always try to cross-cancel as your first step.
So in this problem, the 2 and 8 cross-cancel to 1 and 4.
Also, watch out for your signs. In this problem we have a negative times a positive so we know that our answer will be negative.
Now we can multiply across the numerators and across the denominators.
So we have 5 · 1 which is 5 and 4 · 3 which is 12.
So our answer is -5/12.
Be very careful with your signs!
