Highlights
Rearranging the Linear Equation
00:01:38
Demonstration of how to rearrange the linear equation for either x or y to prepare for the substitution method.
Introduction to Graphs and Intersections
00:00:00
Explanation of visualising a circle and a line from algebraic equations and the use of simultaneous equations to determine their intersection points.
Substitution and Solving the Quadratic
00:02:30
Substituting the linear expression into the circle equation to create a quadratic equation, tidying it up, and factorizing to find potential values for y.
Calculating Coordinates of Intersection
00:05:49
Using the calculated y values to solve for x, resulting in two distinct coordinates representing the points where the line intersects the circle.
