A 270° counter clockwise rotation is the same thing as 90° clockwise- since all 3 of the points are in quadrant 3 (both points negative) it’ll end up in quadrant 2 (x negative, y positive). When you rotate a point 90° you basically just switch the x and y values and change the negative sign to match the quadrant it’s in so for each point (for example (-9,-1)) it would be (-1,9).
Part B: L(6,7) M(3,1) N(-1,3)
Step by step explanation: To translate something just add or subtract from the x and y values making sure to apply the same change to all of the points if they are in the same shape (or instructed otherwise).
To write this expression as a positive exponent we use this rule of exponents: xa=1x−a. 5−3=15−−3=153. Use this rule for exponents: xa=1x−a. 5−3=15−−3=153=1125.
