Question

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

Answer 1

5- (-25) = 30 which is the x distance

30 * 7/10 = 21

-25+21 = -4 the x coordinate

110--20 = 30 which is the y distance

30 * 7/10 =21

10 -21 = -11 is the y coordinate

(-4, -11) is the point to split the segment into a 7:3 ratio
