The correct equation would be Y=1/2x+4 :)
This is true because both equations have the same slope therefore they are parallel and the equation above also includes point (-6,1).
The slope is 5/1 because u find a point (4,20) and then like “simplify” it, 1/
he would charge $4 for half a gallon of milk
For #21, you would just equal 2x +24 = 3x- 12 then simplify and get your answer
