The point P(4,5) divides AB internally in the ratio 1:1, where A(2,3) and B(x,y). What are the coordinates (x,y)?
(6,7)
Dividing AB in the ratio 1:1 means P is the midpoint of AB.
Midpoint formula: \(P = \left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right)\)
For the x-coordinate: \(\frac{2 + x}{2} = 4 \Rightarrow 2 + x = 8 \Rightarrow x = 6\)
For the y-coordinate: \(\frac{3 + y}{2} = 5 \Rightarrow 3 + y = 10 \Rightarrow y = 7\)
So B = (6,7).
Hence, the answer is (6,7).
A line passes through the point (4,3) and intercepts the x-axis at 8. Find its y-intercept.
