The rate of change of the linear equation is 
Explanation:
The given two coordinates are
and 
To determine the rate of change, let us use the formula,

Substituting the coordinates in the equation, we get,

Simplifying, we have,

Dividing, we get,

Thus, the rate of change of the linear equation is 
The right answer is:

Step-by-step explanation:
The rate of change of a line is the steepness of the line or how close is the line to being vertical.
The more steeper the line of graph is, the more is the rate of change
The given graph has to be observed thoroughly, we can see that the graph has the most rate of change (i.e. the more close to being vertical) between 4 and 6
So,
The right answer is:

That would be D because it is the only one which passes the vertical lione test.

Answer:
18a(2bc + 3d)
Step-by-step explanation:
36abc + 54ad
Step 1: Find the Highest Common Factor of each
36abc = 2×2×3×3×a×b×c = 18a × 2bc
54ad = 2×3×3×3×a×d = 18a × 3d
HCF = 2×3×3×a = 18a
Step 2: Factor out with HCF
18a(2bc + 3d)
