Question 536642
m=		  1/ 4					
							
Plug value of  the slope  and point (4	,-7	) in
Y 	=	m	x 	+	b		
-7.00	=	4*1/4    	+	b			
b=	-7	-	1    				
b=	-8      						
So the equation  will be							
Y 	=	 1/4	x 		-8  

-------
m=		3      					
							
Plug value of  the slope  and point (	5	,	6	) in
Y 	=	m	x 	+	b		
6.00	=	5*3    	+	b			
b=	6	-	15    				
b=	-9      						
So the equation  will be							
Y 	=	3    	x 		-9    		

you follow the same steps for the others
