We have a piecewise function.
Therefore, to find the function, we must evaluate each domain separately.
We have then:

For
x \leq -2:
The function for this domain is:

y = -3

For
-2 \ \textless \ x \leq 2:
The function for this domain is:

y = mx + b
Where,

b = -3 m = (y2 - y1) / (x2 - x1) m = (1 - (-7)) / (2 - (-2))

m = (1 + 7) / (2 + 2) m = 8/4 m = 2
Substituting:

y = 2x - 3

For
x\ \textgreater \ 2:
The function for this domain is:

y = 5
