Math Problem Statement

determine the coordinate of a point 1/4 the distance from (-8,10) to (4,-6)

Solution

To determine the coordinates of a point that is 14\frac{1}{4} of the distance from (8,10)(-8, 10) to (4,6)(4, -6), we can use the section formula for dividing a line segment internally.

Step 1: Identify the coordinates

Let A=(8,10)A = (-8, 10) and B=(4,6)B = (4, -6).

Step 2: Use the section formula

The section formula for dividing the line segment joining two points A(x1,y1)A(x_1, y_1) and B(x2,y2)B(x_2, y_2) internally in the ratio m:nm:n is:

(x,y)=(mx2+nx1m+n,my2+ny1m+n)(x, y) = \left( \frac{mx_2 + nx_1}{m+n}, \frac{my_2 + ny_1}{m+n} \right)

For this problem, the ratio m:n=1:3m:n = 1:3 because the point is 14\frac{1}{4} of the distance from AA to BB.

Step 3: Substitute the values into the formula

x=14+3(8)1+3=4244=204=5x = \frac{1 \cdot 4 + 3 \cdot (-8)}{1+3} = \frac{4 - 24}{4} = \frac{-20}{4} = -5 y=1(6)+3101+3=6+304=244=6y = \frac{1 \cdot (-6) + 3 \cdot 10}{1+3} = \frac{-6 + 30}{4} = \frac{24}{4} = 6

Step 4: Write the final coordinates

The coordinates of the point that is 14\frac{1}{4} of the distance from (8,10)(-8, 10) to (4,6)(4, -6) are (5,6)(-5, 6).
