2y = -6x + 42.....in y = mx + b form, the m stands for the slope
y = -6/2x + 42/2....reduce
y = -3x + 21.....so the slope is -3
First, rearrange the equation so it's in slope intercept form, (y=mx+b)
like this: 2y=6x+42
Divide 2 on both sides of the equation, to end up with y=-3x+21.
The slope of the line is -3!

Hoped this helped :)
