To graph the equation y = -0.5x - 4, you can start by plotting the y-intercept, which is -4 on the y-axis. Then, use the slope of -0.5 to find another point on the line. Since the slope is negative, you would move down 0.5 units for every 1 unit you move to the right. Connect these two points with a straight line to complete the graph of the equation.
y = -0.5x - 4.
Set x = 0 (cover up the x term). The equation is now y = -4. So A = (0, -4) is one point on the graph.
Set y = 0 (cover up the y term). The equation is now 0 = -0.5x -4. So 0.5x = -4 of x = -8. So B = (-8, 0) is another point on the graph.
Mark the two points, A and B, on the graph and join them together using a straight edge.
The graph shifts downward (negative y) by 9 units.

y = -4x The y-intercept is zero. That is, the graph passes through the origin.
