It was actually developed to sketch lines on digital plotters but due to its extensibility and versatility, it was found to be useful for computer graphics as well. The equation of a straight line is usually taught in the form: y = mx + c. which succinctly expresses the fact that if we plot y against x and the variables obey a relationship of this form we will obtain a straight line graph with gradient or slope m and intercept (where the line crosses the y-axis) c (fig 1) . This defines a function.The graph of this function is a line with slope − and y-intercept −. Line … Work out the equation of the line that is parallel to the line y = 5x - 3 passes through (-2, -4) [3] 16. For, a straight line may be specified by giving its slope and the coördinates of one point on it. The straight-line cost c(g|S) of an element g ∈ G is the length of a shortest straight-line program over S computing g. The cost is infinite if g is not in the subgroup generated by S. A straight-line program is similar to a derivation in predicate logic. Ax + By + C = 0, where A, B are not both 0. Line 3 : Multiply numerator and denominator of 'x' coefficient with 2.

In fig the two endpoints are described by (x 1,y 1) and (x 2,y 2).The equation of the line is used to determine the x, y coordinates of all the points that lie between these two endpoints. Notice that if the line passes through the origin, its equation would reduce to y = mx. Line 5 : Algebraic Simplification. The general equation of a straight line is \(y = mx + c\), where \(m\) is the gradient and \((0,c)\) the coordinates of the y-intercept. X = 2.3^6. The C program for fixed point iteration method is more particularly useful for locating the real roots of an equation given in the form of an infinite series. (Theorem 8.3.)
