Number 10. Is 5 because start with the parethesis . So , 13 -2 is 11 than do the 6+ 3 because we move from left to right which is 9 . . So 9+ 11 is 20 than do the exponent which is 25 . So 25-20 equals 5
when x=3, y=11 and when x= -2, y=11 3a+b=11 -2a+b=11 | * -1 3a+b=11 2a-b=-11 ------------ 5a=0, a=0:5, a=0 ⇒ b=11 y=11 for every x So ( 1,11) or (2,11) are also points on the graph
