The questions asks to find the point that divides the interval AB ( A(-7, 5), B(3, 1) ) into the ratio 3:1
I'm looking at the answer but I can't work out why they changed 3:1 to 3:-1 and therefore get a different answer to me
Hello, chancey!
You could baby-talk your way through this one . . .
Find the point that divides the line segment into the ratio
given:
We want a point which is the distance from to
. . . . . . . . . . . . . . . .
. .
To go from to , we'd move:
To go three-fourths the distance, we'd move:
Hence, is: .
Of course, this is basically Earboth's solution.
