Final answer:
The slope of Line A is -3.
Step-by-step explanation:
The slope of a line can be determined by examining the coefficient of x in the equation for the line. In the given equation, 3x - 2y + 5 = 0, the coefficient of x is 3. This means that for every increase of 1 unit in the x-coordinate, the y-coordinate will decrease by 3 units.
Therefore, the slope of the line is -3.
