Hi there! The formula for finding the slope of the line is y2 - y1 / x2 - x1. That means subtract the first y-coordinate from the second y-coordinate and the first x-coordinate from the second x-coordinate. Let's plug in the values: 5 - 5 / -1 - 2. When you subtract them, you get 0/-3 or just simply 0. Because of this, that makes a zero slope, which means the y-axis value stays the same no matter what, which makes a horizontal line. The answer is zero slope.
