Answer:
f(9)=54
Step-by-step explanation:
Subsitute 9 for x in f(x)=6x

(-1,1.5) because you add both ys and both xs then divide by two to find the middle
Answer:
I think it is 3(x+1) not sure but try it(it is a graph answer)
Answer:
(-1, -1/2)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates and divide by 2
( -11+9)/2 = -2/2 = -1
To find the y coordinate of the midpoint, add the y coordinates and divide by 2
(0+-1)/2 = -1/2
(-1, -1/2)
