STRAIGHT LINES - NCERT
ncert.nic.inSTRAIGHT LINES 169 Example 3 Prove that every straight line has an equation of the form Ax + By + C = 0, where A, B and C are constants. Proof Given a straight line, either it cuts the y-axis, or is parallel to or coincident with it. We know that the equation of a line which cuts the y-axis (i.e., it has y-intercept) can be put in the form y = mx + b; further , if the line is parallel to or ...
