Can someone help pls <3

y = -x + 1

Step-by-step explanation:

Any point on an angle bisector has equal distance to both sides

Bisector line slope = rise/run = -1    (rise=run and moves from left to right)

equation: y = mx + b

y = -x+b

pass (2.-1)

-1 = -2 + b     B = 1

y = -x+1  

check: (y- -1)/(x-2) = -1

y+1 = -x+2

y = -x + 1

one set of data has more variation than the other. hope this !

the answer is 21%.
