Ugh helpme plz i need to turn dis in now

Answer:

By using the 90 degree clockwise rotation formula, we are able to determine that the answer is (7, 6)

Step-by-step explanation:

The formula for 90 degree clockwise rotation is

(x,y)--->(y,-x)

The reason why our -6 turns into a positive is because the negative was replacing that negative therefore making it positive.

Hope this helps!

I'll leave the rest of the formulas I have in my notes for you!

180 degree rotations

(x,y)--->(-x,-y)

90 degree counterclockwise

(x,y)--->(-y,x)

270 degree rotation

(x,y)--->(y,-x)
