first you take the x1 and subtract it from x2( 3-2) then you take the y1 and subtract it from the y2 (-4-1) then you divide the difference of x1 - x2 and y1 - y2. you should have -1/5 which then becomes the slope,
your final equation should look like this: y=-1/5x+b.

x2 - x1/ y2 - y1 So...
3= x1
-2=x2
-4=y1
1 = y2
And just plug them in from there :)
