Answer:

B(5, -1)

Step-by-step explanation:

"When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative." - https://calcworkshop.com/

B(-1, -5), -1 = x, -5=y

B(y, x) = B(-5, -1)

B(-y, x) = B(5, -1)

B(5, -1)
