coordinate Geometry

The eq of straight line l is 5x+6y+30=0.K is the point (3,-1). Find

(a) the coordinates of the point where the line l crosses the x-axis;

(b) the coordinate of the point M, at which the line l intersects the line x=2;

(c) the eq of the line passing through K and having the same gradient as l;

(d) the eq of the line passing through K and having a gradient of 0
