y = - 2x - 1

By inspection, you can see that the graph is a straight line

with a slope of -2, and its y-intercept is -1.

-- Place a point on the y-axis at y=-1, and another point at (1, -2).

-- Place your straightedge along both points, connect them, and

extend the line-segment as far in either direction as you like.

You can view an image below showing you how it would be graphed.

No translation will invert a quadratic graph.

The graph shifts downward (negative y) by 9 units.

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.

y= -5

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.

y=x+1 there for answer is 2
