Answer:
A is incorrect! <u>B. should be the correct answer</u>
Step-by-step explanation
After some research, i found that the correct answer is most likely <u><em>B. a regression line and trend line are equivalent terms</em></u>
<em />
<em>A trendline and a regression can be the same. </em>
<em> A regression line is based upon the best fitting curve Y= a + bX Most often it’s a least-squares fit (where the squared distances from the points to the line (along the Y-axis) is minimized). </em>
<em> It can be quadratic or logistic or otherwise, but most often it is linear. </em>
<em> A trendline is often constructed by smoothing of the results, making it less peaked. (often by using a moving average); but can also come from ARIMA projections or curve fitting techniques (such as regression).</em>

For an equation to pass through the origin, (0,0) must be a solution of the equation. So, for the first one,
(0, 0) must satisfy the equation and we can solve for the value of r₁ as shown below.
Since the second equation of the circle also passes through the origin, we use the same steps from the first one.
Thus, we have the values for r₁ and r₂ as 20 and 34, respectively.
Answer: r₁ = 20 and r₂ = 34
