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.
Answer:
392
Step-by-step explanation:
m = 8 and n = 14
Substituting the values of m and n in the question, we get :
7m + 3mn
=( 7 x 8) +(3 x 8 x 14)
= 56 + 336
= 392
60 miles in total.
to find percentages, you divide the part by the whole, so 33/60 = .55, which you then move the decimal over two places and read as a percentage
Option d is the correct answer
- 3x + 4y = - 11
y = 2x - 4
-3x + 4(2x - 4) = -11
-3x + 8x - 16 = - 11
5x = -11 + 16
5x = 5
x = 5/5
x = 1
y = 2x - 4
y = 2(1) - 4
y = 2 - 4
y = -2
Solution: (1, -2)
