We will put ur equation in y = mx + b form, and the slope will be in the m position.
14x + 7y = -9
7y = -14x - 9
y = (-14/7)x - 9/7
y = -2x - 9/7
y = mx + b
y = -2x + (-9/7)....as u can see, the -2 is in the m position and is therefore the slope.
Ok so 6 inch is 26 inches and 26×2 is 52 so on the amount of inches is 12
Your question seems incomplete :-(
Answer:
C
Step-by-step explanation:
The equation of a line is given by the formula 
Where
is the x-coordinate (it is given as 5)
is the y-coordinate (it is given as 1), and
m is the slope (it is given as -3)
Plugging in all the info into the formula we have:

From the answer choices, we see that C is the correct answer.
