Explanation

You must know the equation of a line:

y = mx + b

Where: m is the slope, b is the y-intercept, and x and y are an x- and y-coordinate (x,y)

Convert the equation in the question to linear equation format:

\(3x - 2y = 8\)

\(-2y = -3x + 8\)

\(y = \frac{-3}{-2}x + \frac{8}{-2}\).

Since m = slope, the slope of this line is \(\frac{3}{2}\). Hence option D is correct.
