Answer
Point b is (0,0) Point a is (3,-2) Im not doing the second part
Step-by-step explanation:
The product of (x1)^2 is 20

- d is distance, (x_1,y_1) and (x_0,y_0) two points on a coordinate grid.
In our case :

I believe the answer is 4
In order for something to be a function, it cannot have an x-value repeated. Therefore, (1,0) cannot be a possible ordered pair because the function already has a point at x=1 (1,2).
