Slope From Two Points Calculator

There are several ways to find the equation of a line given different information. One of the classic problems in high school math is finding the slope of a line using only 2 points. The most commonly used way to express the equation of a line is the following: $$ y = mx + b $$ Where \(m\) is the slope and \(b\) is the \(y\) intercept. Using two points \((x_1, y_1)\) and \((x_2, y_2)\) it is possible to find the slope (and later the full equation of the line). You can find the line with the following formula: $$ m = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1} $$ The \(\Delta\) symbol is delta, and it means the difference between two numbers. So \(\Delta y = y_2 - y_1\).
It is important to practice these problems on your own, but for now you can use this calculator for help.
