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.

Explore math with our beautiful, free online graphing calculator. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more.

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.

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.

Start by creating a table of values, choosing values of x to substitute in to the equation, to get the corresponding value of y. This will generate sets of coordinates, which you can then plot...

Learn how to plot coordinates and create straight line graphs to show the relationship between two variables. Also, plot graphs that contain a negative coefficient of x.

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

To draw a straight line graph using known points in GeoGebra is a little trickier. First you have to plot the points first. This is done by typing in the points in the form of (x,y) in the input bar. Try …

Determine at least three values of `x` to plot, and work out the values of `y` by substituting for each value of `x`. This will give you coordinates for these points. Plot the points, and draw a …
