Learn how to calculate the equation of a line from a graph, work out the gradient from an equation, and visualise intercepts with this step-by step guide.

Example Find the equation of the line that goes through the points (−1, 3) and (3, 11). Sketch the two points and join them with a straight line.

In fact, this is how you begin the procedure for finding rational points on elliptic curves: Find a single rational point, then find the equation of the tangent line and see where it intersects the ...
