WebFeb 20, 2024 · We can define a straight line with the help of the following equation. y= mx + a Where, (x, y) = axis of the line. m = Slope of the line. a = Interception point Let us assume we have two points of the line ( p1, q1) and ( p2, q2 ). Now, we will put values of the two points in straight line equation, and we get y = mx + a q2 = mp2 ... (1) Scan conversion involves changing the picture information data rate and wrapping the new picture in appropriate synchronization signals.
