GCSE Maths - How to Plot a Straight Line Using a Table of Coordinates #70

The video tutorial explains how to plot a straight line on a graph using a table of values. It provides examples with equations y = 2x + 3 and y + 1/2x = 4, demonstrating how to choose x values, calculate corresponding y values, and plot the points. The importance of using three points to ensure accuracy is also discussed.

Describe the process of labeling your line after drawing it on the graph.

What is the significance of having three points when drawing a straight line?

If you find that your plotted points do not form a straight line, what should you do?
