WEBFeb 21, 2022 · Solution. First, plot the points P( − 1, 2) and Q(3, − 4) and draw a line through them (see Figure 3.5.3 ). Figure 3.5.3: The line passing through P( − 1, 2) and Q(3, − 4). Next, let’s calculate the slope of the line by subtracting the coordinates of the point P( − 1, 2) from the coordinates of point Q(3, − 4).
