Find the linear equation given two points

The video tutorial explains how to find the equation of a line given two points. It starts with an introduction to the slope-intercept form, Y = MX + B, where M is the slope and B is the Y-intercept. The teacher demonstrates how to use the slope formula, M = (Y2 - Y1) / (X2 - X1), by labeling coordinates and calculating the slope. Finally, the tutorial shows how to identify the Y-intercept from the given points, concluding with the complete line equation.

What is the slope of the line if the two points are (0, 3) and (-2, -1)?

How can you determine the Y-intercept from the given points?
