Final answer:

To find coordinates of point P that partitions segment AB in a 5:1 ratio, use section formula (a variant of the midpoint formula) by plugging in coordinates of A and B and applying the given ratio. Other mentioned methods such as distance formula, slope-intercept form, or parametric equations are not applicable in this context.

Step-by-step explanation:

The student is asking for the coordinates of point P such that it divides the segment AB into a specific ratio, which is a commonly asked mathematics problem in high school. The subject asks for the use of mathematical principles to find the segment division according to a given ratio. To solve this, we need the coordinates of points A and B and the desired ratio, which is given as 5:1 in this case. The method typically used here is the section formula (also known as the internally division formula in some regions), which is a direct application of the midpoint formula adjusted to account for the specific ratio in which the segment is to be divided.

To find the x-coordinate of point P, we would use the formula:
xp = (xa × m + xb × n) / (m + n),
and similarly for the y-coordinate:
yp = (ya × m + yb × n) / (m + n),
where (xa, ya) and (xb, yb) are the coordinates of A and B respectively, and m:n is the given ratio (5:1 in this case).

It is not necessary to use the distance formula, slope-intercept form, or parametric equations in this situation, as they do not directly apply to finding the coordinates of a point dividing a segment in a given ratio. This is strictly a problem that should be solved using the section formula derived from the midpoint formula.
