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.

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

To draw a straight-line graph, start with a T-chart of values. Draw neat x- and y-axes (with a ruler!). Plot the T-chart's points on the axis system.

Given random equations of straight lines, practise drawing the graphs of the lines, and then check your answer.

Straight-line graphs represent linear relationships between two variables. This topic involves drawing a line from an equation, calculating the gradient, finding the equation, and using …

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

Calculate the Straight Line Graph If you know two points, and want to know the "y=mx+b" formula (see Equation of a Straight Line), here is the tool for you. Just enter the two points below, the …

Graphing a line in the xy-axis is one of the most basic skills in algebra that you should learn. In this lesson, we are going to go over three methods that are commonly used.
