Youd first need the slope. (i think)
-2 - 0/ 4 - 2 so simplify this
you get -2/2 simplify that.
y = -1x is yuor equation because you dont have a y - intercept. ;)
Two lines are parallel if they have the same slope but a different y intercept. A line with the same slope and y int as another one will be the exact same
Slope in standard form is -a/b, so your slope is 2/3 and your y int is -3
For example:
y=2/3x+1
If x is perpendicular to A and x is perpendicular to B
⇒ A must be parallel to B
Answer: A is parallel to B (Option C)
2-1 reversed is turning it around : 1-2 which equals -1 because there is one left over. B is your answer and hoped I helped!
