Question

Solve the following pair of linear equations graphically:
x + 3y = 6; 2x – 3y = 12
Also find the area of the triangle formed by the lines represented the given equations with y-axis.
​

Answer 1

Answer:

area of required triangle is 18 square units.

Step-by-step explanation:

For equation first..........

X =0,3,6

Y=2,1,0

For equation second...........

X=0,3,6

Y=-4,-2,0

Use formula "1/2bh" for area

take distance on y axis as base

and.... distance between y axis and the point as height

you'll get

1/2*6*6

=3*6

=18sq. units
