2y = 10
y = 10/2
y = 5 <==horizontal
this is a horizontal line. Anytime you have y = an integer, it is horizontal...and if u have x = an integer, it is a vertical line.
You divide 18 with 3 and is going to equal 6 so that should be your constant proportionality
Step-by-step explanation:
The coordinates of point A (2,8) and C (5,2)
