GCSE Maths - How to Find the Gradient Using the Coordinates of Two Points #66

The video tutorial explains how to calculate the gradient between two points using coordinates. It covers the formula for finding the gradient by dividing the change in y by the change in x. The tutorial provides examples, including a practice problem, and demonstrates how to use the method even when a graph is available. The key takeaway is understanding how to apply the formula to find the gradient between any two points, whether given as coordinates or on a graph.

What is the formula used to calculate the gradient between two points when given their coordinates?

• Change in x divided by change in y

• Product of x and y values

• Change in y divided by change in x

• Sum of x and y values

In the example with points (11, 7) and (8, -2), which point is chosen as the second coordinate?

• (11, 7)

• (7, 11)

• (8, -2)

• (2, -8)

What is the gradient between the points (11, 7) and (8, -2)?

• 3

• 4

• 2

• 1.5

When given a graph, what is the first step in calculating the gradient of a line?

• Draw a new line

• Find the y-intercept

• Calculate the midpoint

• Pick any two points on the line

In the example with points (0, -1) and (4, -7), what is the calculated gradient?

• -0.5

• -1.5

• -2

• -1
