The point
is on the graph of the equation.
Explanation:
The equation is 
We need to determine the point
is on the graph.
To determine the point
is on the graph, we need to substitute the point in the equation and find whether the LHS is equal to RHS.
Thus, substituting the point
in the equation
, we get,

Multiplying the terms within the bracket, we have,

Adding the LHS, we have,

Thus, both sides of the equation are equal.
Hence, the point
is on the graph of the equation 
The distributive property is a(b + c) = ab + ac
I believe the 4th one
an=145+an-1 and a1=20
Answer:
This is an example of distribution
Step-by-step explanation:
The reason why is because the equation is linear and if you exclud the y it show that it can distribute.
