y = -2x - 3 This can be found using the formula (y - y1)/(y2 - y1) = (x - x1)/(x2 - x1) and rearranging into the form y = mx + c. Alternatively, it can be found by inspection, note that the line crosses the y-axis at (0, -3), therefore the constant for this line is -3. The gradient can be seen to drop 2 for every 1 it goes across since gradient equals the rise divided by the run (Δy/Δx), then the gradient is negative 2.
