Transformations of Linear Functions Quiz

• A. The graph of the new line is steeper than the graph of the original line, and the y-intercept has been translated down.

• B. The graph of the new line is less steep than the graph of the original line, and the y-intercept has been translated up.

• C. The graph of the new line is steeper than the graph of the original line, and the y-intercept has been translated up.

• D. The graph of the new line is less steep than the graph of the original line, and the y-intercept has been translated down.

A linear equation y = x is graphed on a coordinate plane. The graph of a new line is formed by the equation y = -6x. Describe the transformation that occurred.

• The graph of the new line is reflected across the y-axis and is less steep than the original line.

• The graph of the new line is reflected across the x-axis and is less steep than the original line.

• The graph of the new line is reflected across the y-axis and is steeper than the original line.

• The graph of the new line is steeper than the original line only.

If a linear function is transformed from the parent function f(x) = x by reflecting across the y-axis and translating 7 unit down, write the function that depicts these transformations.

• g(x) = x - 7

• g(x) = x + 7

• g(x) = - x + 7

• g(x) = - x - 7

• g(x) = 2x + 3
