95 ! alicia is writing the program for a video game. for one part of the game, she uses the rule (x, y) → (x – 3, y + 2) to move points on the screen a. what output does the rule give when the input is (-2, 0)? show your work. (2 points) b. what output does the rule give when the input is (3, -4)? show your work. (2 points) c. is the rule a function? (1 point) explain why it is or why it is not. (2 points)

The "rule" being described here is nothing more than the input/output of a mathematical function.

For every input 'x' value supplied, you only need to subtract three to it. For every input 'y' value, you only need to add four to it.

Example: I'll use variable 'm' to represent this function. Variable 'p' will represent the current input point.

m(p) = p[x - 3, y + 4] = p[-7 - 3, 0 + 4] = p[-10, 4]. 'p[]" is just the point.

I tried my best hope that help!

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
