SOLUTION: A line segment is drawn on a coordinate plane with endpoints r(-10,-4) and s(10,11). point t(-2,2) is also on rs. What is the ratio Of the length of rt to the length of ts ?

Question 1010787: A line segment is drawn on a coordinate plane with endpoints r(-10,-4) and s(10,11). point t(-2,2) is also on rs. What is the ratio Of the length of rt to the length of ts ?
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
Distance formula is square root of the sum of the x and y distances squared. They may be done in either direction. The whole distance rs=sqrt (400=2250=sqrt 625=25.
for st it is sqrt (11-2)^2+(10+2)^2=sqrt (225)=15
for rt it is sqrt(2+4)^2+(-2+10)^2=sqrt(100)=10
The ratio is 10/15 or 2/3 ANSWER
