Answer:

  D. y = -1/3x

Step-by-step explanation:

The line through the origin means the equation will be a proportion of the form y = kx. (You can also see this by looking at the answer choices.) The value of k is ...

  k = y/x . . . . . divide the above equation by x

For the given point (x, y) = (-3, 1), the value of k can be seen to be ...

  k = 1/-3 = -1/3

Then the equation for the line is ...

  y = -1/3x . . . . matches D

Which statement regarding the function y=sin(x) is true?
REY [17]
<h2>Answer:</h2>

c. Reflection over either the x-axis or y-axis will change the graph

<h2>Step-by-step explanation:</h2><h3>a. Reflection over the y-axis will not change the graph since sine is an even function.</h3>

This is false because y=sin(x) is an odd function, not an even one. This means that sin(-x)=-sin(x), and a reflection over the y-axis will change the graph.

<h3>b. Sin(x)=sin(-x)</h3>

This is false because we said that sin(-x)=-sin(x)

<h3>c. Reflection over either the x-axis or y-axis will change the graph</h3>

This is true. Since sin(x) is an odd function, then reflection over either the x-axis or y-axis will change the graph as we said in a. So, for f(x):

<u>REFLEXION IN THE X-AXIS:</u>

h(x)=-f(x)

<u>REFLEXION IN THE Y-AXIS:</u>

h(x)=f(-x)

<h3>d. Sin(x)=-sin(x)</h3>

False by the same explanation as b.
