Examine the following systems of equations. Decide for each system which method would be the most efficient, convenient, and accurate: graphing, substitution, elimination, or the equal values method.
Justify your reasons for choosing one strategy over the others. You do not have to solve the systems.

A.
x = - 2y + 6
x = 3 -4y

B
x = 4 - y
y = 3x + 4

C.
a + b = 10
3a -4a = 6

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
