Question 785338
the slope of line joining two points is given by the formula
(y2-y1)/(x2-x1)=m

x1		y1	x2	y2				
1      		-9      	4      	-11    				
								
slope m =		(y2-y1)/(x2-x1)						
(	-11    	-	-9    	)/(	4    	-	1    	)
(	-2    	/	3    	)  				
m=		-  2/ 3						 

A parallel line will have the same slope

(6,k) (-7,-4)
The line joining these points will have slope of -2/3

(-4-k)/(-7-6)=-2/3

(-4-k)/-13=-2/3

-4-k = -13*-2/3

-4-k = 26/3

k=-4-26/3

k=-38/3
