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 if you move 4 units along the x-axis and 5 units up the y-axis?

• (5, -4)

• (5, 4)

• (4, -5)

• (4, 5)

How do you find the midpoint of a line segment that is 6 cm long?

• Measure 3 cm from one end

• Measure 6 cm from one end

• Measure 2 cm from one end

• Measure 4 cm from one end

What are the coordinates of the midpoint of a line segment if it is located at (1, 4)?

• (1, 4)

• (3, 3)

• (2, 5)

• (4, 1)

Which of the following points lies on the line y = -3?

• (6, -3)

• (6, 3)

• (3, 6)

• (3, -6)

What is the y-coordinate of all points on the line y = -3?

• 3

• 1

• 0
