Answer:
All four lines are perpendicular
Step-by-step explanation:
Lines 1 and 2 are parallel
y+8x=−5;x+1/6y=−5
Lines 2 and 3 are parallel
x+1/6y=−5;y=−6x−7
Lines 1 and 4 are perpendicular they intercept
x+1/6y=−5;y+3=1/8(x−1)
All four lines are perpendicular
line 4 is perpendicular to all other lines

Answer:
yes
Step-by-step explanation:
x=3-y
2(3-y)+7y=16
6-2y+7y=16
5y=10
y=2
x=3-2=1
