The ordered pairs are;
A(3, 4), B(-3, 2), C(-2, -4), D(6, -3), and E(0, 0)
Step-by-step explanation:
An ordered pair is the coordinate definition of a point on a coordinate plane that gives the x and y values of the coordinate of the point within parenthesis separated by a comma

Answer: number 4
Step-by-step explanation:
Ok so we can model this like
![1.89+0.25x=3.8](https://tex.z-dn.net/?f=1.89%2B0.25x%3D3.8)
This is because the initial price was 1.89$ for the drink, then for every refill, it was a quarter extra. To solve for x we start by subtracting 1.89 from both sides.
![0.25x=1.91](https://tex.z-dn.net/?f=0.25x%3D1.91)
So now we divide by 0.25 or multiply by 4 and we get
![x=7.64](https://tex.z-dn.net/?f=x%3D7.64)
But x cannot be a fraction. So we round this to the least integer, or 7
