Slope and Y-Intercept Concepts

The video tutorial explains how to write an equation in slope-intercept form. It begins by finding the slope using the formula (Y2 - Y1) / (X2 - X1) with given coordinates. The tutorial then demonstrates how to find the y-intercept by substituting a point into the equation. Finally, it combines these elements to formulate the equation in the form y = mx + b, where m is the slope and b is the y-intercept.

What is the formula used to find the slope between two points?

• X1 plus X2 divided by Y1 plus Y2

• X2 minus X1 divided by Y2 minus Y1
