The gradient of ½ represents the slope or steepness of a line. In this case, a gradient of ½ means that for every 1 unit you move horizontally along the line, you will move ½ unit vertically.
To illustrate this, let's consider a line with a gradient of ½. If we start at the point (0, 0), for every 1 unit we move to the right, we would move ½ unit up. So, if we move 1 unit to the right, we would end up at the point (1, ½). If we move 2 units to the right, we would end up at the point (2, 1).
Alternatively, if we move 1 unit to the left, we would move ½ unit down. So, if we move 1 unit to the left from the starting point (0, 0), we would end up at the point (-1, -½). If we move 2 units to the left, we would end up at the point (-2, -1).
In summary, a gradient of ½ means that the line is inclined at an angle where for every 1 unit you move horizontally, you move ½ unit vertically.
