slope is -3-(-12)/(15-6)=9/9=1
point slope formula y-y1=m(x-x1), where m is the slope and (x1,y1) the coordinates
y-(-3)=1(x-15)
y+3=x-15
y=x-18

Use one of the following POINT-SLOPE equation formulas to get the equation:

    OR       OR          OR     

I've done the hard work in explaining how to arrive at the answer. You now need to do some work too in getting that answer.
