Question
Find the coordinates of the point three tenths of the way from A to B. A= (-4,-8) b= (9,4)
Solution
To find the coordinates of the point that is three tenths of the way from point A to point B, you can use the formula for finding a point on a line segment between two points:
P = A + t(B - A)
where:
- P is the point you're trying to find,
- A and B are the given points,
- t is the fraction of the distance from A to B (in this case, t = 0.3).
First, calculate the difference between the coordinates of points B and A:
B - A = (9 - (-4), 4 - (-8)) = (13, 12)
Then, multiply these differences by t:
t(B - A) = 0.3 * (13, 12) = (3.9, 3.6)
Finally, add these results to the coordinates of point A:
P = A + t(B - A) = (-4 + 3.9, -8 + 3.6) = (-0.1, -4.4)
So, the coordinates of the point three tenths of the way from A to B are (-0.1, -4.4).
