Watch this video to learn about the equation of a straight line. Since we are given 2 points that already lie on the line, using the formula as before, we need to calculate the gradient first.

The straight line through two points will have an equation in the form \(y = mx + c\). Then, we can find the value of \(c\), the \(y\)-intercept, by substituting the coordinates of one point into the ...

Using high school algebra and geometry, and knowing just one rational point on a circle or elliptic curve, we can locate infinitely many others. You’re sitting at the end of a long conference table, ...
