A line contains the points (8, 9) and (–12, –7). Using point-slope form, write the equation of the line that is parallel to the
kozerog [31]
For the answer to the question above,
The slope of the line of the line is calculated through the equation,
m = (y2 - y1) / (x2 - x1) 

Using the first two points in the given,
 m = (-7 - 9) / (-12 - 8) = 4/5

The line parallel to this has also a slope of 4/5. Through the point-slope form, the equation of the second line is,
 y - -15 = (4/5)(x - -5)

Simplifying gives the answer of,
y = (4/5)x -11

Eliminating the fraction, 
5y = 4x - 55

I hope my answer helped you.

(9n + 12) ft + (15n -6) ft
MAXImum [283]
For this case, the first thing we must do is to group similar terms.
 We have then:
 n (9 + 15) + (12-6)
 Rewriting:
 24n - 6 ft
 Answer:
 
(9n + 12) ft + (15n -6) ft = 24n - 6 ft
