Answer:
For the parallel one the gradient will stay the same, so you just need to work out the y-intercept
3=(-12)-6+c
3=12+c
c=-9
equation for parallel line y=-6x-9
Then for perpendicular the gradient is the reciprocal
so you substitute again
3=1/6(-2)+c
3=-1/3+c
c=10/3
the equation for perpendicular is y=1/6x+10/3
The answer is b. see pic for answer
Answer
you would need 24/3 paint to cover the wall.
Step-by-step explanation:
and 24/3 simplified is 8/1.
so you will need 8/1 paint to cover the wall.
