The general algebraic expression to represent a translation has the form:

(x+a, y+b)

Where the points are translated "a" points to the right and "b" points up.

From the given figure, we can see that the point "S" goes from (-6, -3) to (-2, 2)

Then, we can formulate the following expressions, to find "a" and "b":

x-coordinate of point S + a = x-coordinate of point S'

-6 + a = -2

-6 + 6 + a = -2 + 6

a = 4

y-coordinate of point S + b = y-coordinate of point S'

-3 + b = 2

-3 + 3 + b = 2 + 3

b = 5

Then, the algebraic expression that represents this translation is:

(x + 4, y + 5)

Then, the correct answer is the last option
