We will learn how to calculate the gradient of a straight line including parallel and perpendicular lines, and how to quickly sketch a straight line graph with limited information.

Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more.

Learn and revise how to plot coordinates and create straight line graphs to show the relationship between two variables with GCSE Bitesize Edexcel Maths.

The equation of a straight line is usually written this way: (or y = mx + c in the UK see below). y = how far up.

In this section we are looking at Straight Line Graphs, and some of their properties. An activity to practise drawing linear graphs from their equations. Use this activity to explore the idea of …

Straight-line graphs are an essential part of Maths and appear in many problem-solving contexts. This guide will cover coordinates, equations of straight-line graphs, gradients, parallel and …

In this overview, we will start with graphing straight lines, and then progress to other graphs. The only major difference, really, is in how many points you need to plot in order to draw a good …

Maths revision video and notes on the topic of drawing straight line graphs.

To draw the graph, we substitute values into the equation, to calculate the values. Then, we plot the coordinates onto the graphs and join them up with a straight line.

Now see how two points can change the line equation. Try to make: Move the m and b slider bars to explore the properties of a straight line graph. The effect of changes in m. The effect of …
