To express the distance between the point and a point on the line , we start by taking a point on the line. The distance can be calculated using the distance formula:
This simplifies to:
Thus, we can express the objective function in terms of as
The interval of interest for this objective function arises from considering where is located relative to the closest approach to the vertical line at . The closest point can be determined considering the variability in . Since varies as changes, we primarily consider positive values, which gives an interval of
To find the point on the line that is closest to the point , we minimize . Setting the derivative of equal to zero leads to .
Thus, the coordinates for are
At this point, the least distance between point and can be calculated using the distance formula:
So, the least distance rounded to the nearest tenth is approximately
