Slope - Find the Missing Coordinate

Learn how to find a missing coordinate (either x or y) when you're given the slope and two points in this algebra tutorial! Mario's Math Tutoring demonstrates how to use the slope formula (y2 - y1) / (x2 - x1) to set up an equation and solve for the unknown variable. We'll go through two examples, one where the x-coordinate is missing and another where the y-coordinate is missing, providing clear, step-by-step instructions.
