use the ditributive property                         -3(y+3)=2y+3    and thats what ya get                               -3y+-9 =2y+3     then subtract the 2 and add                       +2y      -2y            it to the otherside                             -1y+ -9 =+3  then add the -9 to the other side             +9   +9       next divide by -1                                                -1y= 12 then your anwser is                                              y=-12
To solve an equation that states the slope and a point you must do the folowing:   Slope = 3  and the line goes through the point  (2,9) to put it in y= mx+b form you alreday know the m is 3 because the m is slope and the problem states the slope is 3 an easy way to figure the rest out is to graph it and you`ll find that the y intercept is 3 which means da anwser to da the problem is                                 y = 3x+3
