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.

What happens to the graph of y equals x when the equation changes to y equals x - 9?
The graph shifts downward (negative y) by 9 units.
What describes how to translate the graph of y equals x to obtain the graph of y equals x plus 1 - 2?
3
State the y-intercept for the graph y equals -4x?
y = -4x The y-intercept is zero. That is, the graph passes through the origin.
Graph y equals 3x - 7 what is the y intercept?
-7
Y equals 14 - 2x graph?

What describes the translation of the graph of y equals x2 to obtain the graph of y equals -x2 - 3?
No translation will invert a quadratic graph.
What happens to the graph of y equals x when the equation changes to y equals x - 9?
The graph shifts downward (negative y) by 9 units.
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.
What describes how to translate the graph y equals x to obtain the graph of y equals x plus 1 plus 1?
y=x+1 there for answer is 2
State the y-intercept for the graph y equals -4x?
y = -4x The y-intercept is zero. That is, the graph passes through the origin.
Graph y equals 3x - 7 what is the y intercept?
-7
