The standard equation of a straight line in the slope-intercept form is y = mx + c where m is the slope and c is the y intercept.
3x - 6y = 12 can be re-written as 6y = 3x - 12 or y = 1/2x - 2.
-2 is therefore the y intercept (this is when x = 0)
The x intercept (when y = 0) can be obtained from the equation y = 1/2x - 2 : 0 = 1/2x - 2 : 1/2x = 2 : x = 4.

the slope of the line is -4
Equation of given line: 3x + y = 15 or y = -3x + 15 Slope of given line = coefficient of x = -3 Slope of perperndicular = -1/(slope of given line) = -1 / (-3) = 1/3
