Answer:
The new points to the triangle will be:

Step-by-step explanation:
Because the reflection point is at
, all x values will subtract their distances from
to get their new values. The y values remain the same.
The starting values are:

Point
is 5 units away from
, so we'll subtract 5 from -1 to get the new x value:
, so
.
Point
is also 5 unit away from
, so we'll subtract 5 from -1 to get the new x value:
, so
.
Point
is 7 units away from
, so we'll subtract 7 from -1 to get the new x value:
, so
.
