Given two points find the slope of the line

The video tutorial explains how to calculate the slope of a line using coordinates. It begins by introducing the concept of slope and the importance of x and y values in coordinates. The instructor highlights common mistakes students make when subtracting values and emphasizes the correct method. The video then explains how to label coordinates for clarity and provides a detailed explanation of the slope formula. Finally, an example calculation is demonstrated, showing how to handle double negatives and simplify the result.
