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 ...

If you're given two points — for example, (3, -2) and (1, 6) — you can first use the slope formula to find ... the line equation. Relationship Between Point Slope Form and a Straight Line ...
