www.rastrick.calderdale.sch.uk• Parallel graphs have the same gradient. • Gradients of perpendicular graphs have a product of -1. Questions: 1. The diagram shows a straight line, L 1, drawn on a grid. A straight line, L 2, is parallel to the straight line L 1 and passes through the point (0, −5). Find an equation of the straight line L 2.
Equations of straight lines

Key Point The equation of a straight line with gradient m passing through the origin is given by y = mx. 3. The yintercept of a line Consider the straight line with equation y = 2x+1.

sites.math.washington.eduStep 4: Place a straight-edge perpendicular to the gradient vector and move the straight-edge either in the direction of the gradient vector for maximization (or in the oppo-site direction of the gradient vector for minimization) to the last point for which the straight-edge intersects the feasible region. The set of points of intersection between

www.cs.cmu.edu5.1.3 Exact line search At each iteration, do the best e can along the direction of the gradient, t= argmin s 0 f(x srf(x)): Usually, it is not possible to do this minimization exactly. Approximations to exact line search are often not much more e cient than backtracking, and it’s not worth it.
