Answer:
The given system of equations :
5x − 6y + 30 = 0 ....(1)
5x + 4y − 20 = 0 .....(2)
Consider (1) ,
When x = 0; y = 5
When x = −6, y = 0
Consider (2),
When x = 0; y = 5
When x = 4, y = 0
both the lines intersect at (0,5), so the solution of the given system of equations is :
x = 0; y = 5
Now, vertices of the ∆ formed by the above 2 lines and x−axis are :
(−6,0); (4,0); (0,5)
