Use photo math,, to save your points!
Basically, you plug in -4 for x and -7 for y (since -4 is the x coordinate and -7 is the y coordinate). When doing that, you get:
-14=-16+2
-8+7=-1
im not gonna say the answer, but looking at these equations, you can probably tell if they work or not :)
Congruent angels I’m pretty sure this is the awnser
