REALLY NEED HELP ON THESE 3 MATH QUESTIONS!!! (20 PTS)

Answer 1

1. x² - 6x + 8
   4*2 equals 8 and if you add 4 and 2 it gives you 6
    -4-2= -6
   =(x-4)(x-2)

3. the answer is A
    if you plug in the points into the equation y=x
    y= 1/2x + 4
given point: (4,6) x=4 y=6
    6= 1/2(4)+4
    6=6
