Answer:
im not really sure but i think its b
Step-by-step explanation:
It’s £4.5
Convert 25 to a decimal so 0.25
0.25 x 18 = 4.5
The ordered pairs are (1,-1) (1,-2) (2,-3) (2,-4).
This is not a function because in order to be a function, every x value needs to have one and only one y value. You can see here that the x values have two y values, so it is not a function.
