Q. The graph of y=x y=|x| is scaled vertically by a factor of 15 \frac{1}{5} .\newlineWhat is the equation of the new graph?\newlineChoose 11 answer:\newline(A) y=15x y=\frac{1}{5}|x| \newline(B) y=5x y=-5|x| \newline(C) y=x+5 y=|x+5| \newline(D) y=x5 y=|x-5|
  1. Understanding vertical scaling: To determine the equation of the new graph, we need to understand what it means to scale a graph vertically by a factor of (1)/(5)(1)/(5). Scaling a graph vertically by a factor of (1)/(5)(1)/(5) means that every yy-value of the original graph is multiplied by (1)/(5)(1)/(5).
  2. Scaling the original equation: The original equation is y=xy = |x|. To scale this graph vertically by a factor of (1)/(5)(1)/(5), we multiply the entire right-hand side of the equation by (1)/(5)(1)/(5). This gives us the new equation y=15xy = \frac{1}{5}|x|.
  3. Checking the answer choices: Now we need to check the answer choices to see which one matches our new equation. The correct answer choice should be y=15xy = \frac{1}{5}|x|.
  4. Matching the new equation: Looking at the answer choices, we see that choice (A) y=15xy = \frac{1}{5}|x| matches the equation we derived for the new graph.
