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 
.
