Step-by-step explanation:
Hey there!
Well by looking at the graph we can eliminate choices C and D,
this is because we can see the y-intercept is above of 0.
So that leaves A and B.
A. y = [x] + 5
B. y = [x] + 4
Choice A. is correct because line start at the start of the line not the end.
Hope this helps :)
