How to write an equation given two points using point slope formula - coolmath

The video tutorial explains how to find a linear equation given two points. It covers two methods: the slope-intercept method and the point-slope method, focusing on the latter. The tutorial demonstrates how to calculate the slope using the formula (Y2 - Y1) / (X2 - X1) and how to find the Y-intercept by substituting one of the points into the equation. The final linear equation is derived by combining the slope and Y-intercept.

What is the significance of the slope (M) and the Y-intercept (B) in a linear equation?

Describe the process of finding the Y-intercept after determining the slope.
