Answer:

Step-by-step explanation:
A point is written using the form (X,Y), so the first number is the X and the second number is the Y.
Replace x and Y in the given equation with the given point:
y ≤ 3x+1
9 ≤ 3(2) +1
9 ≤ 6 +1
9 ≤ 7
9 is not less than or equal to 7, so the point (2,9) does not satisfy the inequality.
I'm assuming the given log equation is 
If so, then the exponential form is 
This is because the general form
transforms into 
For both equations, the 'b' is the base.
