Final answer:
Any two distinct values can serve as the values of r for the equation y=xr in the absence of additional constraints or context. In a straight-line graph scenario, these would correspond to different slopes of the line through the origin.
Step-by-step explanation:
The question appears to be about finding two values of r that satisfy a given mathematical equation, y = xr. The context provided suggests a relation to other concepts such as correlation coefficient and circular motion, but those are unrelated to the core mathematical equation presented.
Without additional constraints or a specified range for r, any two distinct values can be selected since the equation y = xr forms a straight line through the origin with slope r in Cartesian coordinates. We find r by picking two distinct values for x and computing the corresponding y values, thus determining two individual slopes, r, where the line passes through these points.
Generally, if a specific context is given such as a scatter plot with a best-fit line or a circular motion scenario, the value of r would have a particular meaning such as the correlation coefficient or radius, respectively, which would guide the selection of feasible r values. However, as the question stands, we have the liberty to choose any r values for the purpose of demonstrating the solution process.
