alright find the distance between the x values and the y values and seperate each into that ratio 1:1 A to B is (6,12) to (15,-4) disatnce from 6 to 15 is 9, ratio would be 4.5:4.5=1:1 distance from 12 to -4 is 16, ratio would be 8:8=1:1 so the point would be (4.5,8)
b. 5:2 5+2=7 alright A to C (6,12) to (20,12) distance from 6 to 20 is 14, 14/7=2, 2 times 5=10 distance from 12 to 12=0, so same coordinate the point is (10,12)
c. 2+3=5
C to B C is (20,12) and B is (15,-4) distance from 20 to 15 is 5, so 2 is the x value distance from 12 to -4 is 16, 16/5 times 2=32/5 the point is (2,32/5)
