Explain how you can find the constant of proportionality from a graph representing a proportional relationship when it shows a p
1 answer:
For a proportional relationship, the constant is found dividing all values of y by each respective value of x.
<h3>What is a proportional relationship?</h3>A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
The constant can be represented as follows:
Hence the constant is found dividing all values of y by each respective value of x.

Answer:
A
Step-by-step explanation:
We can write this as Sinx by "flipping" the .
So we will have:
From basic trigonometry, we know the value of of sine is of the angle
<em>But when is sine negative? </em>Either in 3rd or 4th quadrant. But the answer has to be between 0 and , <em>so we disregard 4th quadrant.</em>
<em />
<em>To get the angle in 3rd quadrant, we add π to the acute angle of the first quadrant (which is π/4 in our case).</em><u><em> Thus we have:</em></u>
A is the right answer.
