Slope and Fraction Concepts

The video tutorial explains how to find the slope of a line between two points using the slope formula. It begins by introducing the concept and assigning variables to the given coordinates. The tutorial then demonstrates substituting these values into the formula and simplifying the result. Finally, it verifies the solution using graphing software, showing that the calculated slope matches the graphical representation.

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

• y1 minus y2 over x1 minus x2

• x1 minus x2 over y1 minus y2

• y2 minus y1 over x2 minus x1

• x2 minus x1 over y2 minus y1
