Complete Question:

Alicia 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)?

B)What output does the rule give when the input is (3,-4)?

C) Is the rule a function? Explain why it is or why it is not

Answer:

a. The output is (-9,4)

b. The output is (0,0)

c. See Explanation

Explanation:

Given

Rule: (x,y)->(x - 3, y + 4)

Solving (a):

Inputs:


x = -6


y = 0

The outputs is as follows;


x => x - 3


x => -6 - 3


x => -9


y=> y + 4


y=> 0 + 4


y=> 4

Hence:

The output is (-9,4)

Solving (b):

Inputs:


x = 3


y = -4

The outputs is as follows;


x => x - 3


x=>3-3


x = 0


y=> y + 4


y=>-4+4


y=>0

Hence:

The output is (0,0)

Solving (c):

The function is a rule and the rule is that:

It shifts the graph left by 3 units and up by 4 units
