A quadtriatel is said to contain perpendicular diagnols if four go 90 degree angles are formed at the intersection of these lines
From the first equation we get
y=4x-15
put the value of y in the second equation
3x+2(4x-15)= -8
3x+8x-30= -8
11x=22
x=2
now put x=2 in any one eqn , say in first
4(2)-y=15
8-y=15
-y=7
y=-7
hope you understand!
