Writing the equation from a graph

The video tutorial explains how to derive the equation of a graph in the form Y = MX + B. It covers identifying the Y intercept, which is where the graph crosses the Y axis, and calculating the slope using a slope triangle. The tutorial concludes with writing the final equation using the determined slope and Y intercept.

What does the slope represent in the equation of a line?

Write the equation of a line given a slope of -3 and a Y intercept of 2.
