Question 625714
x+y=2  ......................1
2x-y=7  .....................2

Generate y co-ordinates for various values of x and plot both lines.
Find the x & y intercept points by plugging x=0,y=0 in both equations.								
equation I								
when x=	0	y=	2	,(	0	,	2	)
when y =	0	x=	2	,(	2	,	0	)
Equation 2								
when x=	0	y=	7	(	0	,	-7	)
when y =	0	x=	3.5	(	3.5,0	)
