GCSE Maths - Finding the Equation of a Straight Line From 2 Sets of Coordinates #69

This video tutorial explains how to find the equation of a line given two coordinates. It covers the process of calculating the gradient (slope) and the y-intercept to form the equation in the format Y = MX + C. The tutorial includes two example problems to demonstrate the method, emphasizing the steps of finding the gradient, using it to calculate the y-intercept, and forming the final equation.

What is the first step in finding the equation of a line given two coordinates?

How do you calculate the gradient (M) of a line using two points?

How do you handle negative coordinates when calculating the gradient?

Explain how to find the value of C after determining the gradient M.

What is the formula used to find the equation of a line in slope-intercept form?

What is the final equation of the line that passes through the points (-2, 3) and (2, 5)?

What steps would you take to find the equation of a line that passes through the points (0, -3) and (8, -7)?
