How do you define Straight Lines?
Straight line represents straights objects with negligible width and depth. The angle (say) θ made by the line l with positive direction of x-axis and measured anti clockwise is called inclination of the line. Obviously 0° ≤ θ ≤ 180° If θ is the inclination of a line l, then tan θ is called the slope or gradient of the line l. We know that graph of general equation of first degree in two variables, Ax + By + C = 0, where A, B and C are real constants such that A and B are not zero simultaneously is a straight line. Thus, General Equation of Straight line is Ax + By + C = 0, where A, B and C are real constants such that A and B are not zero simultaneously.
