How to graph? i am unsure how to do this piece wise function

Answer 1

Answer:  see graph - the blue dot is a hole

Step-by-step explanation:

y = x/2

Graph this equation.  It is in slope-intercept form where b = 0 and m = 1/2. Place a hole at x = 2   (coordinate 2, 1)

y = 4 at x = 2

Plot this coordinate (2, -4).

Note: The line jumps over the hole.
