Revise how to plot a linear equation graph. Learn how to read x and y coordinates from a graph in this BBC Bitesize maths KS3 guide.

If an equation can be rearranged into the form \(y = mx + c\), then its graph will be a straight line. In the above: \(x + y = 3\) can be rearranged as \(y = 3 - x\) (which can be re-written as \(y = ...

Now make a graph. Be sure it is an "x-y scatter" and not "line" - see how good Open Office is? They even use the dumb names that Excel uses for types of graphs. Only plot the X and Y values.

The two graphs, like a dot plot, have both an x- and y-axis. You can calculate the spread of the dots by subtracting the minimum value from the maximum value on the chart. The center of the ...

Playfair explained his approach using a graph that showed the expenditure of the Royal Navy over the preceding decades. Time is on the horizontal x-axis, money is on the vertical y-axis; the line ...

We discuss a comment on a previous post stating that the text of labels on the vertical axis of graphs must be horizontal by discussing the pros and cons of four possible positions for these labels.
