Understanding Slope and Y-Intercept

The video addresses confusion from previous independent practice by explaining how to write equations in the form y=mx+b. It provides step-by-step solutions for three example problems, focusing on finding the slope and y-intercept, even when zero is not present in the table. The teacher emphasizes problem-solving skills and offers further assistance if needed.
