Answer:

-1

Step-by-step explanation:

The midline is the average of the maximum and minum.

0.5 = (y + 2) / 2

1 = y + 2

y = -1

The minimum is at y=-1.

For the given problem the value of ymin is -1.

What is minimum?

Suppose maximum is denoted by ymax and minimum is denoted by ymin ymid represents the mid.

By mid point theorem y

mid   = (ymax + ymin)/2

How to find yminimum?

Given ymid  = 0.5

         ymax  = 2

          ymin  = y

substituing values 0.5 = (2+ y)/21 = 2+yy = -1

yminimum  = -1
