y = (1/2)x
The slope is change in y / change in x = 1/2 = rate of change
In the table....note that the rate of change is the same......every time y changes by 1, x changes by 2
Also...if we let x = 0 in the function, then y = (1/2)(0) = 0
So. (0,0) is on the graph of the function...this is the y intercept
Which is the same point as in the table
So....
The y intercepts and rate of change are the same ⇒ "B"
