GCSE Secondary Maths Age 13-17 - Graphs: Coordinates - Explained

The video tutorial covers three main tasks: identifying the coordinates of point B, finding the midpoint of line AB, and drawing the line with the equation y = -3. The instructor explains how to determine coordinates, calculate midpoints, and plot lines on a graph, emphasizing the importance of understanding the relationship between x and y coordinates. The tutorial also includes tips on labeling lines and understanding the significance of constant y-values in linear equations.

What are the coordinates of point B?

How do you find the coordinates of the midpoint of line segment AB?

What is the equation of the line that is drawn at y equals minus 3?

Explain why the line y equals minus 3 has a y-coordinate of minus 3 for all points on it.

What would you do to draw the line where x equals 5?
