Question

taking 2cm = 1unit on both axis solve the equation graphically : x+y-6=0, 4x-2y-6=0​

Answer 1

Answer:

Answer:

2x+y=6

⟹y=6−2x

Let, x=1, then y=6−2(1)=4

Similarly, when x=2,y=2

x−2y+2=0

⟹x=2y−2

Let, y=0, then x=2(0)−2=−2

Similarly, when y=2,x=2

Plotting the above points on the graph, we get, the vertices of the traingle, i.e. A(2,3),B(3,0),C(−2,0)

∴ Area of the triangle = 1/2

×5units×2units

=5 sq. units
