Step-by-step explanation:
For : (0,3) (2,2)
The equation is in slope intercept form. y=mx+b
The y intercept is 3.
The slope is 1/2.
Moving one unit down and 2 units to the right, we get (2,2)
For : (0,-2) (1,0)
The y intercept is -2.
The slope is 2.
Moving 2 units up and 1 unit to the right, we get (1,0)
