Subject: Equations of a Straight Line with multiple points

I'd like to create a formula that create multiple straight lines. It all has to be in one single formula. For example:

p1(0,0)
p2(1,4)
p3(2,9)
p4(5,9)

The slope should always be 0 and at any given point the y value should jump to the y value.

Is this possible at all? If not, would it be possible if I just do a linear interpolation. If so, how can I get the correct formula?

thanks
