lower:
(9-0)/(4-1)=9/3=3
upper right:
(-1-5)/(6-(-3))=-6/9=--2/3
I linked the ACTUAL answer in the comments on a website i found to the answer to your question. get the app socratic it helps. it’s legit i promise
Assuming equation 2 is y = (2/3)x-6, then the answer is A) Parallel.
Solve 2x-3y = 6 for y and you'd get y = (2/3)x-2. The slope here is 2/3 as it is for equation 2 as well. The slopes are the same but y intercepts are different, so the lines are parallel.
