Need to format the equation in $y=mx + b$ .

$3x−2y = 12$

$3x -12 = 2y$

$y = 3/2x -12/2$

$y = 3/2x -6$

The slope is $3/2$ or $1 1/2$ . The $x$ -intercept is at $y = 0$ , hence

$2y = 3x -12$

$2(0) = 3x -12$

$0 = 3x - 12" "$ (isolate $x$ for the intercept)

$12 = 3x$

$12/3 = (3x)/3$

$4 = x$

The intercepts are
