I don't know the answer to the question but I just wanted to say I love your profile picture. I love Quackity :) <3
First you need to find the slope.
You do this by adding x to both sides to get 3y=x-12
Then, you divide by three on both sides to get y=1/3x -4
to find the new y intercept you insert the point and the slope in the equation
2=1/3(18)+b
You multiply 1/3 and 18 to get 2=6+b
Finally you subtract 6 on both sides to get -4=b.
This means that the equation of the line is the same as the given line
In my opinion the new coordinates are
A' (-3, -5)
(-2,6)
for example
x+1/2y=1
the ordered pair i will use is the first one. (-2, 6)
so
(-2) + 1/2(6)=1
from there it is a simple add/subtract and multiply/divide math problem.
1/2(6)=3
so
(-2) + 3 = 1
yes this ordered pair works for the solution meaning it is the answer.
