Aline that includes the points (n,-6) and (-9,-4) has a slope of -15. what is the value of n?
n=

hey guys i need an answer fast! ?
!

n=-8.86

Step-by-step explanation:

Slope will determine the direction and the steepness of a function. It could be either increasing/decreasing depend on minus or plus. The formula for slope is

m= (y2-y1)/ (x2-x1)

If you add (n,-6) and (-9,-4)  to the equation, it will be:

m= (y2-y1)/ (x2-x1)

-15= (-6--4)/ (n--9)

-15= (-2)/ (n+9)

-15(n+9) = -2

-15n - 135=-2

-15n= -2 + 135

n= -133/15

n= -8 13/15= -8.86

addition

step-by-step explanation:

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
