How many points need to be removed from this graph so that it will be a function?
2 answers:
3 points
do you see how the x value -3 has two points (-3,2) and (-3, 3)
the x value should never repeat in order for this graph or any graph or table to be a function
(-3,2) and (-3, 3)
one has to go....
(1,4) and (1,-4)
one has to go....
(2,-2) and (2,-4)
one has to go....
C.) 3 points because you can't have 2 points on the same y axis line.

1 x 64 = 64
2 x 32 = 64
4 x 16 = 64
8 x 8 = 64
16 x 4 = 64
32 x 2 = 64
64 x 1 = 64
The sum of -3 and a number equal to -91 is -88
If you're finding slope, the answer is 5/3
