The midpoint of a line segment is (1,5). if one endpoint is (4,7), what is the ither endpoint?

Let

By definition, the coordinates of the midpoint are the average of the coordinates of the endpoints:

We deduce, solving for the coordinates of A:

Plug your values:

Which evaluates to

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
