36/12 = 3

Answer = 3
The slope of the line is 
Explanation:
Given that a coordinate plane with a straight line passing through the points
,
and 
We need to determine the slope of the line.
The slope of the line can be determined using the formula,

Since, the points
,
and
lie on the straight line and the slope of all the points in a straight line have the same slope.
Hence, let us consider the points
and 
Let us substitute these points in the slope formula, we have,

Simplifying, we get,

Dividing, we get,

Hence, the slope of the line is 
The initial amount of money placed in the savings account
Answer:
f(g(-64)) = -190
Step-by-step explanation:
The functions are not well written.
Let us assume;
f(x) = x+1
g(x) = 3x+1
f(g(x)) = f(3x+1)
Replace x with 3x+1 in f(x)
f(g(x)) = (3x+1) + 1
f(g(x)) = 3x + 2
f(g(-64)) = 3(-64) + 2
f(g(-64)) = -192+2
f(g(-64)) = -190
<em>Note that the functions are assumed but same method can be employed when calculating composite functions</em>
