Arnold is writing a program for a video game for one part of the he uses the rule (x, y) (x+7,y-3) to move points on the screen a. what output does the rule give when the input is (-10,0) b. what output does the rule give when input is(-7,3) c. is the rule a function?

We are given rule

when

input is (x,y)

then output is (x+7 , y-3)

(A)

we are given

input is (-10,0)

so, x=-10 and y=0

now, we can find output

x+7=-10+7=-3

y-3=0-3=-3

so, output is (-3,-3)

(B)

we are given

input is (-7,3)

so, x=-7 and y=3

now, we can find output

x+7=-7+7=0

y-3=3-3=0

so, output is (0,0)

(C)

We know that

x+7 and y-3 are translation rules of function

so, this is function

true
