Answer 2

Answer:

2x−y−4=0 …(i)

y=2x−4

When x=1,y=2×1−4=2−4=−2

When x=2,y=2×2−4=4−4=0

When x=3,y=2×3−4=6−4=2

Step-by-step explanation:

Mark the above points on graph. Join them.

It is clear from the graph that the two lines intersect at (1,−2).

So the solution of the given equations are x=1 and y=−2.

The area of the triangle formed by these lines and Y axis =1/2 ×base×height

=1/2×3×1

=1.5sq. units

Hence area of the triangle is 1.5sq. units.
