Answer:
I think the answer is C but I'm not 100% sure
For this case we have the following equation:
y = 100 - 8.9x
Where,
x = the number of hours of use
For 11 hours of use we have x = 11.
Substituting:
y = 100 - 8.9 * (11)
y = 2.1%
Answer:
the best prediction of the percent of remaining power for a battery after 11 hours of use is:
y = 2.1%
Answer:

Step-by-step explanation:
The line y= -3/4+6 in the comments has slope -3/4. A perpendicular line will have the negative reciprocal of -3/4. It's 4/3.
To write the equation, substitute 4/3 and the point (3,9) into
