1 Find the equation of the straight line that passes through the points(3,-1)and (-2,2)mgiving your answer in the form ax+by+c=0.
Hence find the coordinates of the points of intersection of the line and the x-axis.
2 The point A has coordinates (2,_5).The straight line 3x+4y-36=0 cuts the x-axis at B and the y-axis at C.Find
(a) the equation of the line through A which is perpendicular to the line BC;
(b) the perpendicular distance form A to the line BC
(c) the area of triangle ABC
