Question

Draw the graph of $2x-y-1=0$ and $2x+y=9$ on the same graph. Use $2cm=1$ unit on both axes.
Write down the co-ordinates of the point of intersection of the two lines.

• A. $x=3.5,y=4$
• B. $x=4.5,y=4$
• C. $x=1.5,y=4$
• D. $x=2.5,y=4$

Answer 1

The correct option is D $x=2.5,y=4$

Plotting $2x-y-1=0$ and $2x+y=9$ in the graph, we get
the point of intersection as $(2.5,4)$
