Question

The endpoints of JK are J(–25, 10) and K(5, –20). What is the y-coordinate of point L, which divides JK into a 7:3 ratio?

Answer 1

y = -11.

Explanation:

If point L divides JK into a 7:3 ratio, you can say that, technically, JK has been divided into 10 parts.

The y-coordinates of JK span over 10 + 20 = 30 units. 30 / 10 = 3. 3 * 3 = 9. -20 + 9 = -11. So, the y-coordinate of point L is -11.

The x-coordinates of JK span over 25 + 5 = 30 units, 30 / 10 = 3. 3 * 7 = 21. -25 + 21 = -4. So, the x-coordinate of point L is -4.

When you put it together, the coordinates of point L are (-4, -11).

Oh that wasn't the question but uh the y-coordinate is -11 hope this helps!
