Answer with explanation:
The two system of equation which are graphed on coordinate plane :
→x -y =1
y=x-1
→y-x=1
y=x+1
⇒Comparing with Slope intercept form of Line which is y= m x +c,
→m=1 for both the lines
As, the two lines has same slope , so they are parallel.Parallel lines never Intersect.
⇒The two system of equation have no solution as:
[tex]\frac{1}{-1}= \frac{-1}{1}\neq \frac{1}{1}[/tex]
Option A:→ No Intersection Point
