Interactive graph - slope of a line You can explore the concept of slope of a line in the following interactive graph (it's not a fixed image). Drageither pointA(x1,y1)or pointB(x2,y2)to investigate how the gradient formula works. The numbers will update as you interact with the gra...
The gradient (also called slope) of a line tells us how steep it is. To find the gradient: Have a play (drag the points):
Vertically, a step up is positive, a step down is negative. Horizontally, a step to the right is positive, to the left is negative. Ahorizontal linehas a gradient of0. Avertical lineis infinitely steep. The gradient isundefined. Drawing a graph form the equation y = mx + c. Identify ...
(a) The gradient of the line through R and Q is 0.5Show how you can work this out from the graph.___(b) What is the equation of the straight line through R and Q?(c) Write the equation of a line that is parallel to the straight linethrough R and ...
We report an experiment in which people were asked to make a judgement about the gradient of a simple line graph. As part of the MultiVis project on data visualisation for blind people our aim was to discover how accurately linear graphs can be rendered using relatively simple technology: rais...

gradient in the composition of the copolymer chains that are formed along the reaction is by variations in comonomer feed composition during the reaction, forcing the situation to influence the composition of the chains that form as conversion advances; that leads to the use of a semibatch ...
For each k find the value of λ that minimizes (1.6)f(x(k)−λ∇f(x(k))) This procedure is known as a line-search. The reader will note that this is also a minimization problem. However, since x(k) is known, it is a one-variable minimization problem in the step size λ....
