Alivia is writing the program for a video game. for one part of the game she uses the rule (x, y)➡️(x-3,y+4) to move points on the screen. (a) what output does the rule give when the input is (-6,0)? show your work (b) what output does the rule give when input is (3,-4)? show your work (c) is the rule a function? explain why or why not? ?

A) the output would be -9,4 because using the rule Alivia created (x,y)➡(x-3,y+4) -6 (which is the x value) subtract 3 equals -9. 0, which is the y value plus 4 equals four.

b) The output would be 0,0 because using the same rule 3 subtract 3 is 0 and -4 plus 4 is 0.

c) Honestly I tried to determine whether the rule was a function and I am having a hard time determining. But I can tell you that x values cannot have more than one y value while y can have more than on x value.

please vote my answer brainliest. thanks!
