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.

What is the transformation of the graph of y equals x2 to obtain the graph of y equals -x2 plus 3?
First, reflect the graph of y = x² in the x-axis (line y = 0) to obtain the graph of y = -x²; then second, shift it 3 units up to obtain the graph of y = -x² + 3.
Graph the line y equals 5?
y= -5
What describes how to translate the graph of y equals x to obtain the graph of y equals x plus 1 - 2?
3
How can you translate the graph of y equals x to obtain the graph of y equals x-4 plus 2?
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
