Question 87785

        slope of the line through the points (0,5)&(-3,-4)=M= y2-y1/x2-x1
                                                            =--4-5/-3-0 
                                                            =-9/-3
                                                            =3   
             slope of the line  perpendicular to the given line m1.m2=-1
                       slpoe of the required line = m2=-1/3
