now....for writing equation chose any 2 given points.

let . one of them be (X1,Y1) and another be (X2,Y2)

now .....put the values of X1,Y1,X2 and Y2 in this formula and u will get required equation of line.

(X-X1)/(X1-X2)=(Y-Y1)(Y1-Y2)

where:m is the slope of the line, found using methods described in Slope of a Line (Coordinate Geometry).x and y are the coordinates of any point on the line.
