Question 463639
-6x + 0 = y

y = -6x

6y -12x + 126 = 30
6y-12x+96 =0 divide by 6
y -2x + 16 = 0
substitute 

-6x -2x+16 =0
-8x = -16
x =2

y = -6 * 2
y = -12 

put them is standard form

y = mx + b


y = -6x + o    m--> -6
6y -12x + 126 = 30
6y =12x - 96
y = 2x - 16   m--> 2

no the two lines are not parallel m1 does not equal m2
