Answer:
any number, n, multiplied by 1 is less than n + 1, so A = 1, B = any number
For example, 1 % 7. 1 * 7 = 7. 1 + 7 = 8
Also, having one of the variables be a decimal can make the numbers smaller.
For example, 28 * 0.5 = 14. 28 + 0.5 = 28.5
Ay^2+2ay-3a
a(y^2+2y-3)
a(y-1)(y+3)
The conclusion is valid
it is a systematic random sample
and the second one is a line graph (I think)
