Question

What are the x- and y- coordinates of point p on the directed line segment from k to j such that p is three-fifths the length of the line segment from k to j? x = (startfraction m over m n endfraction) (x 2 minus x 1) x 1 y = (startfraction m over m n endfraction) (y 2 minus y 1) y 1 (40, 96) (85, 105) (80, 104) (96, 72)

Answer 1

The coordinate of P is (A) ( 40, 96).

What are coordinates?

• Coordinates are two integers (Cartesian coordinates) or a letter and a number that point to a specific place on a grid known as a coordinate plane.
• A coordinate plane has four quadrants and two axes: x (horizontal) and y (vertical) (vertical).

To find What are the x- and y- coordinates of point p on the directed line segment from K to J:

It can be seen from the figure the coordinates of K and J:

• K ( 160 ,120) and J (-40 , 80)

The coordinates of P can be determined as:

$x=\frac{m}{m+n} (x_{2}-x_{1})+x_{1} } \\y=\frac{m}{m+n} (y_{2}-y_{1})+y_{1} }$

So, as the P point divides the line into three-fifths of the length,

• KP = (3/5)KJ  
• JP = (2/5) KJ

Which gives the ratio as 3: 2.

m:n = 3:2

• x = (3/5) (-40 -160) + (160)
• x = 40
• y = ( 3/5)(-40) +120
• y = 96

Therefore, the coordinate of P is (A) ( 40, 96).
