Question

Two linear equations are depicted in the graph . If $(x,y)$ is the point of intersection of the system of equations, calculate $x-y$.

• A. $-4$
• B. $-2$
• C. $2$
• D. $4$

Answer 1

Answer: (D)

$4$

As per given graph the point of intersection $(x,y)$

But seeing graph the point of intersection is $(3,-1)$

Then $x=3$ and $y=-1$

So, $x-y=3-(-1)=3+1=4$
