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 standard equation for a parabola is ... The latus rectum, or focal chord, is a line segment that passes through the focus of the parabola and is perpendicular to the axis of symmetry.

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.
