Answer:
it can be solved using the formula hope it will hep you
Y=mx+b
m=slope
given
y=6x-9
m=6
the slope is 6
The mean would be 5
Reason for this is that the mean is when all data is summed up then divided by how many data points there are
So 4+4+7=15
Then divide by 3 would equal 5
I hope this helps!
