Question 604088
6.5x+10y=-20
6.5	x	+	10	y  	=	-20							
y=	- 13/20	x  	-2									
Assume values of x and plug in the equation to get values of y.													
Plot the points													
x	0	20	-20										
y=	-2	-15	11										
(x,y)	(0,-2),(20,-15),(-20,11	)




-6x+3y=18
-6	x	+	3	y  	=	18							
y=	2      	x  +	6										
													
Assume values of x and plug in the equation to get values of y.													
Plot the points													
x	0	1	2										
y=	6	8	10										
(x,y)	(0,6),(1,8),(2,10)
