The video tutorial covers graph sketching, focusing on understanding slopes and perpendicular lines. It explains the concept of opposite reciprocal slopes and how they differ from parallel lines. The tutorial also demonstrates finding the Y-intercept using a given point, emphasizing the importance of slope-intercept form in graphing.

Explain the concept of opposite reciprocal slopes in relation to perpendicular lines.

How can you find the equation of a line if you are given a point and the slope?
