GCSE Secondary Maths Age 13-17 - Shapes & Area: Properties of 2D Shapes - Explained

The video tutorial explains how to find the equation of a straight line using the formula Y=MX+C. It covers identifying the Y-intercept and calculating the gradient by using the rise over run method. The tutorial also discusses the importance of understanding this concept for exams and provides a breakdown of the marking scheme for such questions.

What does the 'M' represent in the equation Y = MX + C?

• The Y-intercept

• The gradient of the line

• The X-intercept

• The constant term

Where does the line cut the Y-axis in the given problem?

• At -3

• At 0

• At -6

• At 6

How is the gradient of a line calculated?

• Sum of X and Y

• Run over rise

• Difference of X and Y

• Rise over run

What is the final equation of the line L?

• Y = 3X - 6

• Y = -3X + 6

• Y = -3X - 6

• Y = 3X + 6

How many marks are allocated for correctly identifying the gradient in the exam question?

• No marks

• One mark

• Two marks

• Three marks
