Step-by-step explanation:
To find : Which equations represent functions?
Solution :
Function is defined as the relationship between two variables in which one variable is dependent s.t. for one variable we have the value of other.
From the given options,
A.
This is a function of variable x and y forming a linear equation.
B.
This is not a function as there is only one variable x.
C.
This is not a function as there is only one variable x.
D.
This is not a function as there is only one variable y.
E.
This is not a function as there is only one variable x.
Therefore, Option A is correct.

The type of transformation that has happened is a translation. Translation is when the image's size nor shape changes after transformation. every point in the image moves the same distance in the same direction.
the equation for the translation mentioned is;
T4, -5(x,y)
this means that every point in the image has moved down by 5 units and moved to the right by 4 units.
Point A to Point E
Point A - (-4,-1)
after translation (x+4, y-5) = (-4+4,-1-5)
= (0,-6) these are the coordinates of point E.
the other three points too have moved the same distance and direction as point A did.
