Answer:
this would be B.
Step-by-step explanation:
it crosses the y axis at positive 3. so has to be +3. this leaves b and c, it is a negative slope so it is Y= -2x+3.
You have to isolate x. First you start off by adding the like terms which is -3x and -x. By adding them you get -4x.
8 - 4x = 12
Then you subtract 8 on both sides since it is positive to isolate x.
-4x = 4
Then you divide -4 by both sides and get x=4/-4
4/-4 is simplified to -1 so the answer is x= -1
Not sure what dimensions means but this is what I got out of it , hope it helps !
