Question

a( , )
b( , )

Explanation:

Step1: Determine coordinates of A

Point A is on the y - axis (x - coordinate is 0) and at y=-3 (since it's 3 units below the origin on the y - axis). So coordinates of A are (0, - 3).

Step2: Determine coordinates of B

To find coordinates of B, we look at the x - coordinate (horizontal) and y - coordinate (vertical). From the origin, moving left 4 units (x=-4) and up 3 units (y = 3). So coordinates of B are (-4, 3).

Answer:

A(0, - 3), B(-4, 3)
