Answer:
The answer is below
Step-by-step explanation:
A linear graph has an equation of the form:
y = mx + b,
where y and x are variables, m is the slope (rate of change) of the graph and b is the y intercept (value of y when x is 0).
Given that:
2x -2y = 4 , 3x + 2y = 6
The matrix form of the equation is:
AX = B
Answer: D) a+bi
Where both a and b are real numbers.
In your textbook, you might see to indicate that they are real numbers.
An example would be 7+13i, where a = 7 and b = 13.
