Answer:

The slope is -9

and the interpretation is that the percentage that drops on the battery per hour is 9%

Step-by-step explanation:

Generally, the equation of a straight line can be represented by the formula;

y = mx + b

where m is the slope and b is the y-intercept

With respect to the given equation, the slope is -9

What it means is that the percentage that drops per hour on the battery is 9%
